Fenrir User Manual

Fenrir is a modern command line screen reader written in Python3.

It has a modular structure, a flexible based driver model, is highly configurable and easy to customize and extend (see Developer Manual (fenrir_development_manual)).

Please see the following pages for the current (fenrir_current_version) and Git (fenrir_git_version) version of Fenrir.

Support and Requirements

Fenrir requires several drivers to interact with the operating system.

  Speech Drivers

A speech driver is for communication with the text to speech system like Speech-Dispatcher (#SpeechDispatcher) or Espeak (http://espeak.sourceforge.net). \ See section Speech (#Speech) in ''settings.conf'' for more information.

  SpeechDispatcher

This driver is used by default. It uses Speech-dispatcher as its backend.

Dependencies:

•   Speech-dispatcher (installed and configured, Documentation (https///devel.freebsoft.org/speechd#sec2))

•   Python-speechd

  Espeak

Uses Espeak via Python bindings.

Dependencies:

•   Espeak or Espeak-ng

•   python-espeak (https///launchpad.net/python-espeak)

  Generic

This invokes speech via a sub-process. This is almost the same as using the commandline. The performance depends on the overhead of the speech synthesis application but it is really flexible.

Dependencies:

•   Espeak or Espeak-ng

The Requirements are flexible, they depend on the configuration in settings.conf.

  Dummy

this is just for debugging, logs are output to the screen and logged as well.

  Sound Drivers

To play sound icons and similar.\ See section Sound (#Sound) in ''settings.conf'' for more information.

  Generic

This driver is used by default.

Dependencies:

•   Sox (http://sox.sourceforge.net/) with opus support The Requirements are flexible, they depend on the configuration in settings.conf.

  Gstreamer

if you prefer to use Gstreamer for sound output.

Dependencies:

•   Gstreamer >= 1.x

•   Glibc

  Dummy

this is just for debugging, logs are output to the screen and logged as well.

  Input Drivers

Input drivers are to capture keyboard shortcuts issued to the screen reader
See section Keyboard (#Keyboard) in ''settings.conf'' for more information.

  Evdev

This driver is used by default.

Evdev is the low level input device framework for Linux.

Dependencies:

•   python-evdev >=0.6.3

•   pyudev

•   loaded uinput kernel module

•   exclusive access to the input devices Read permission to the following files and services:

•   /dev/input

•   /dev/uinput

  Screen Drivers

The job of a screen driver is to get the information of current screen content.\ See section Screen (#Screen) in ''settings.conf'' for more information.

  VCSA

This driver is used by default. For Linux VCSA devices. These exist on any current standard installation of Linux.

Dependencie s:

•   python-dbus Read permission to the following files and services (or run as root):

•   /sys/devices/virtual/tty/tty0/active

•   /dev/tty[1 - 64]

•   /dev/vcsa[1 - 64] (VCSA manpage (https///linux.die.net/man/4/vcsa))

•   read Logind DBUS

  Braille Drivers

This is for Braille support. Braille is currently a work in progress and is planned for the Fenrir 2.0 release.\ See section Braille (#Braille) in ''settings.conf'' for more information.

  BRLTTY

This driver is used by default. It uses BrlTTY (brltty) to communicate with with a Braille device.

Dependencies:

•   BrlTTY (configured and running, Documentation (http://mielke.cc/brltty/doc/Manual-BRLTTY/English/BRLTTY.html))

•   python-brlapi (configured, Documentation (http://mielke.cc/brltty/doc/Manual-BrlAPI/English/BrlAPI.html)) ## Currently supported platforms

Currently Fenrir completely supports the following Platforms:

•   Linux TTY Support for further Systems are planned.

Installation

Fenrir can run without installation. It just requires the dependencies are installed first.

We recommend to try it out before installation to be sure everything works and prevent yourself from experiencing a non-talking environment.

  Try Out

Fenrir does not require installation. You can try it and make sure everything works before you decide to install. In this way you can be sure that your system doesnt break or stop talking. for that you can just grab the code and run as root ''src/fenrir/fenrir'' (in foreground) or ''src/fenrir/fenrir-daemon'' (in background, used by systemd for autostart)

  Install it

  Documented operating systems

  Arch Linux

For Arch there are PKGBUILDs in the AUR:

•   fenrir (https///aur.archlinux.org/packages/fenrir/)

•   fenrir-git (https///aur.archlinux.org/packages/fenrir-git/)

  Manual

1.  Download the latest stable version from the Fenrir-Project (https///linux-a11y.org/index.php?page=fenrir-screenreader) site.

2.  Unpack the archive

3.  Check the needed Dependencys by running check-dependencys.py (https///github.com/chrys87/fenrir/blob/master/check-dependencies.py) script

4.  install the missing dependencies an standard installation requires the following:

    •   python3 >= 3.3 (and all the following is needed for python3 )

    •   python3-speechd (screen)

    •   python3-dbus (screen)

    •   python3-evdev >= 0.6.4(input)

    •   python3-daemonize (background service)

    •   python3-brlapi (braille)

    •   python3-pyenchant (spellchecker)

    •   your language for aspell (aspell-<lang>) (spellchecker)

    •   sox (sound)

    •   For an individual installation see Support and Requirements (#Support%20and%20Requirements) or consult the Readme (https///github.com/chrys87/fenrir/blob/master/README.md))

5.  run "install.sh" as root

this installs Fenrir as the following

    * Application:''/opt/fenrir''
    * Settings:''/etc/fenrir''
    * Sound Icons:''/usr/share/fenrir/''

to remove Fenrir just run uninstall.sh as root

  Git

if you want to get the latest code you can use git to get a development snapshot:

    git clone https://github.com/chrys87/fenrir.git

  Auto Start

To start Fenrir once: systemctl start fenrir

To enable auto start on system boot: systemctl enable fenrir

First Steps

If you are using Fenrir for the first time you may want to take a look at these resources:

•   Keybindings (#Keybindings)

•   Tutorial Mode (#Tutorial%20Mode)

Features

  Commands

  Keybindings

Normal commands can be invoked in two ways: 1. Using a Metakey (FenrirKey (#Fenrir%20Key)) 2. Shortcuts with a single key

See section Keyboard (#Keyboard) in ''settings.conf'' for more information. #### Fenrir Key

The Fenrir Key is for invoking screen reader commands. Fenrir can utilize more than one FenrirKey at the same time. By default the following keys are used: 1. Insert 2. KeyPad Insert 3. Meta (Super, Windows)

  Script Key

To invoke "Scripts" the Script Key is mandatory. The shortcut is encoded in the filename of the script. See Scripting (#Scripting) #### Desktop Layout

•   set bookmark 1 - X #### Set mark

How to set a mark: 1. navigate with review or textcursor to the position you want to set the mark. Attention: if a review cursor is set, that is the prefered. If you want to use text cursor, be sure that you are not in review mode. 2. press shortcut for ''set mark'' you can set two marks (begin and end). Some commands allow some simpler usecases just using the whole line if only one mark is set. you may want to try this out. #### Get text between marks

To get the text that is currently between your marks press shortcut for ''marked text''.\ #### Remove Marks

You can remove all current marks by pressing the shortcut for ''remove marks''. Changing the screen also removes the marks. ### Screen Interaction

Fenrir provides several methods to interact with the current screen. #### forward keypress

This just forwards the next shortcut to the screen Fenrir shortcut or not. This is useful if the currently pressed shortcut is also in use by Fenrir. #### Clipboard

Fenrir provides a clipboard with multible items represented by a list. You navigate throught the list and paste the selected clipboard. ##### copy marked to clipboard

To copy something to the clipboard you need to set one or two marks. if you set one mark, the text between the mark and your current cursor is copied to clipboard. Setting two marks just copies the text between the marks into the clipboard. If you copy something it is always placed as the first item on your clipboard. ##### clear clipboard

You can remove all items from the current clipboard by ''clear clipboard'' functionality. ##### first clipboard

This moves quick to the first item of the clipboard. ##### last clipboard

This moves quick to the last item of the clipboard. ##### previous clipboard

Go to previous item in the clipboard. ##### next clipboard

Go to next item on the clipboard. ##### read current clipboard

Read the content of the current item of the clipboard. ##### paste clipboard

Pass whatever item is currently selected by first, last, prev or next clipboard commands. if no special clipboard is selected the (last copied) is used. ##### export clipboard to file

This allows you to export the current clipboard to a configurable filepath. This is useful to share the clipboard with a graphical desktop. ##### import clipboard from file

Import a clipboard from a configurable file. This is useful to share the clipboard with a graphical desktop. ### Quick Settings

Fenrir supports window mode, a window is a partial area of the screen. #### Create Window

To create a window you need to do the following: 1. set a beginning mark (as the start of the window) 2. set an end mark (where the window should end) 3. press ''set window application'' shortcut. Now Fenrir ignores anything outside of the window.\ #### Remove Window

You can remove the window by pressing ''the clear window application'' shortcut. Now Fenrir will read everything on the screen again. ### Tracking Modes

Different types of tracking are currently supported See section Focus (#Focus) in ''settings.conf'' for more information. #### Cursor Tracking

This follows the text cursor. This is the typical way an application works. This is used by:

•   almost any shell such as (Bash, Zsh, sh)

•   vim

•   nano

•   emacs

•   mutt

•   tintin++ #### Highlight Tracking

In some applications there are no text cursors. In those applications cursor changes are represented by different colors or attributes (underlined or bold). This mode tracks and announces these changes for you. This is used by:

    * wifi-menu
    * dialog
    * alpine

  Tutorial Mode

Fenrir provides a Tutorial mode. When you enter tutorial mode, screen reader commands are intercepted and explained instead of executing them. ''Arrow up'' and ''Arrow Down'' let you navigate through a list of all available commands with shortcuts and description. Pressing escape leaves the tutorial mode.

  Information

  Time

Announces the current Time. #### Date

Announces the current Date. #### Bookmarks

Bookmarks provide quick access to part of the screen without the need to navigate to the area. By default Fenrir provides 10 bookmarks. Those can be set and accessed via shortcut. This is useful for status lines or other information where the position does not change. ##### set Bookmark X

You need to set the bookmark first. For that you have to set one or two lines for use. 1. Set marks (one or two) 2. press shortcut for ''set bookmark X''. X represents the number 1 - 10. ##### read Bookmark X

If a bookmark is set you can access the area just by pressing the ''bookmark X'' shortcut. X represents the number 1 - 10. Bookmarks are dynamic. That means the content changes with the screen. ##### clear Bookmark X

to remove a bookmark just press the ''clear bookmark X'' shortcut. X represents the number 1 - 10. Afterward the bookmark is no longer available. #### cursor position

You can get information about the current cursor and its position by using the "cursor position" functionality. #### indent current line

Announce the current indent level of the current line. It represents the number of trailing spaces of the line. #### current screen

Reads all the current screen from the beginning to the end. #### current screen before cursor

Reads current screen from the beginning of the screen to the current cursor position. #### current screen after cursor

Read anything after current cursor position to the end. #### cursor read to end of line

Read from the current cursor position to the end of the current line. #### cursor column

Read the current X position of a cursor (column of the current line). #### cursor line number

Read the current Y position of a cursor (line number). #### present first line

Reads just the first line. this is maybe useful for status information. #### present last line

Presets the last line. This is maybe useful for status information. #### last incoming

Repeat the last automatically incoming text. ## Input

  Echo

Fenrir provides different methods of echoing content:

•   Word: Will speak each word after you push space

•   Character: speak any letter you type on the screen

•   Delete Character: speaks the character prior to the cursor when you push backspace ### Silence on Key press

  Spellchecker

Fenrir has a built-in spellchecker, it can invoke automatically while typing or be called by a shortcut. Commands to add or remove the current word to the dictionary are included. As using the spellchecker is enhanced usage. You will need dictionary aspell-<language>. See section General (#General) in ''settings.conf'' for more information. #### spell check

Invokes the spellcheck on the word that contains the Review or text cursor. #### add word to spell check

Adds the word under the Review or Text cursor to the dictionary. #### removes word from spell check

Removes the word under the Review or Text cursor from the dictionary. ## Announcements

  Emoticons

If you want to replace ":)" emoticons with "smile" in speech you can use this feature. It can be toggled on or off. You can define emoticons in a dictionary, please see Emoticon Dictionary. See section General (#General) in ''settings.conf'' to see how to enable or disable this feature.

  Time

Announce the time at periodical increments, To track the time easily. You can define 2 different ways of time announcements. 1. periodic 2. on fix minutes

Example periodic, every 20 minutes "delaySec=20":

    [time]
    enabled=True
    presentTime=True
    presentDate=True
    delaySec=20
    onMinutes=
    announce=True
    interrupt=False

Example on fix minutes in an hour. example every quarter "delaySec=0" and "onMinutes=00,15,30,45":

    [time]
    enabled=True
    presentTime=True
    presentDate=True
    #delaySec is repected bevore onMinutes so it need to be set to 0
    delaySec=0
    onMinutes=00,15,30,45
    announce=True
    interrupt=False

  Promoted List

Promoted Lists are a nice feature if you are away from your computer or performing more longer tasks. you can define a list of words which you want to hear a sound icon for after a period of inactivity. Example if the word "Chrys" appears after 120 Seconds of inactivity: [promote] enabled=True
inactiveTimeoutSec=120 list=Chrys See section Promote (#Promote) in ''settings.conf'' for more information. ### Punctuation

Fenrir handles punctuation levels and names for you with several provided dictionaries.

See levelDict See punctuationDict ## Braille

Fenrir provides Braille support in Version >= 2.0. See section Braille (#Braille) in ''settings.conf'' for more information. ### braille flush

If a message appears on the Braille device you can flush it to get back to the review- or system cursor ### Braille pan left

If a line is longer than your Braille devices you can move the view (called panning) to the left. So you can read stuff without the need to move the review- or system cursor. ### Braille pan right

If a line is longer than your Braille devices you can move the view (called panning) to the right. So you can read stuff without the need to move the review- or system cursor. ### braille return to cursor

When you have finished reading the line on the Braille device using panning, the focus can be returned to the current used cursor by using "return to cursor" command. ## Dictionary

You can make use of different kinds of built-in dictionary's. A dictionary has a name and list of keys and values separated by :===: Example: [customDict] Chrys:===:Chrys is cool lollipop:===:lolli that means that every instance "chrys" is displayed, speech will say Chrys is cool. "lollipop" is spoken as "lolli". Before making changes to a dictionary we recommend making a backup of your current dictionary in case future updates overwrite your local changes. ### Punctuation

  Level

The punctuation level dict contains lists with "what punctuation is spoken in what level". the default one looks like this: [levelDict] none:===: some:===:.-$~+*-/\@ most:===:.,:-$~+*-/@!#%^&()[]}{<>; all:===:!"#$%& '()+,-./:;<=>?@[\]^_`{|}~ the level "none" has no values. so it should not speak any punctuation (sadly this is not respected by every TTS system) if "some" is the current level the following are spoken: dot dash dollar tilde plus star slash backslash at. same for most and all, you can add new levels. if you cycle punctuation levels they are recognized. the default punctuation level is set in settings.conf. The default is "some". #### Punctuation

The punctuation dictionary "[punctDict]" contains how the punctuation is spoken. Example: [punctDict] :===:line
speaks an as "line".
[punctDict] :===:underscore speaks an as underscore. for question mark an ? is appended to the word that the TTS system can announce the question correctly.
### Custom

The dict "[customDict]" is just for your own use, it just replace the key with the value without any special functionality. This might be used to fix incorrectly spoken words, make words more common, shorter or just for fun. :) ### Emoticons

The Emoticons dictionary "[emoticonDict]" by default contains some emoticons. it can replace ":)" with "smile" or "XD" with "loool" Making chat more colorful. A nice feature with this dictionary is that you can toggle the substitution on or off during run time or in settings.conf. This is useful because while doing programming or other serious work you want to hear colons and perryns not smiles. # Configuration

You can configure Fenrir in the following places (ordered by priority): 1. Commandline Parameters ''-o'' see Set settings coption (#Set%20settings%20coption) 2. /etc/fenrir/settings/settings.conf see Settigns (#Settings) 3. <sourceTree>/config/settings/settings.conf see Settigns (#Settings) 4. hard coded defaults ## Commandline Arguments

  Set settings option

You can specify options that overwrite the setting.conf. This is done with ''-o <list of options> parameter. The list of options have the following syntax fenrir -o "section#setting=value;section#setting=value"

For example changing the sound driver to gstreamer and disabling Braille
fenrir -o "sound#driver=gstreamerDriver;braille#enabled=False=False" or change the debug level to verbose fenrir -o "general#debugLevel=3" You can find the available sections and variables here <#Settings> See Syntax #settings.conf syntax (#settings.conf%20syntax) ### settings.conf syntax

the syntax of the settings.conf (#Settings) is quite simple and similar to a "*.ini" file, there are 4 different elements. 1. Sections 2. Settings 3. Values 4. Comments

A comment starts with a # and is ignored by Fenrir. # this is a comment To group settings we have sections. A section can look like this: [Section] A setting looks like this: settingName=Value

Example: sound (#sound) # Turn sound on or off: enabled=True # Select the driver used to play sounds, choices are genericDriver and gstreamerDriver. # Sox is default. driver=genericDriver

  Settings

  Sound

The sound is configured in section ''sound (#sound)''.

Turn sound on or off: enabled=True Values: on=''True'', off=''False''

Select the driver used to play sounds. The genericDriver using Sox is the default.

    driver=genericDriver

Available Drivers:

•   ''genericDriver'' using the generic driver, for Fenrir <1.5 just use ''generic''

•   ''gstreamerDriver'' using the gstreamer, for Fenrir <1.5 just use ''gstreamer''

These are the pack of sounds used for sound icons. theme=default By default we ship two sound packs. 1. ''default'' opus encoded, for newer Sox versions 2. ''default-wav'' wav encoded, just for compatibility Sound packs are located at /usr/share/sounds/fenrir/

Sound volume controls how loud the sounds for your selected sound pack are. volume=1.0 Values: ''0.0'' is quietest, ''1.0'' is loudest.

  Generic Driver

The generic sound driver uses shell commands for play sound and frequencies.

''genericPlayFileCommand'' defines the command that is used to play a sound file. genericPlayFileCommand=<your command for playing a file> ''genericFrequencyCommand'' defines the command that is used playing frequencies. genericFrequencyCommand=<your command for playing a frequence>

The following variables are substituted in ''genericPlayFileCommand'' and ''genericFrequencyCommand'':

•   ''fenrirVolume'' = the current volume setting

•   ''fenrirSoundFile'' = the sound file for an sound icon

•   ''fenrirFrequence'' = the frequency to play

•   ''fenrirDuration'' = the duration of the frequency

Example genericPlayFileCommand (default) genericPlayFileCommand=play -q -v fenrirVolume fenrirSoundFile Example genericFrequencyCommand (default) genericFrequencyCommand=play -q -v fenrirVolume -n -c1 synth fenrirDuration sine fenrirFrequence ### Speech

Speech is configured in section ''[speech]''. Turn speech on or off: enabled=True Values: on=''True'', off=''False''

Select speech driver, options are speechdDriver (default),
genericDriver or espeakDriver:

driver=genericDriver

Select the driver used to generate speech output.

    driver=speechdDriver

Available Drivers:

•   ''genericDriver'' using the generic driver, for Fenrir <1.5 this is not available

•   ''speechdDriver'' using speech-dispatcher, for Fenrir <1.5 just use ''speechd''

•   ''espeakDriver'' using the espeak directly, for Fenrir <1.5 just use ''espeak''

The rate selects how fast Fenrir will speak. rate=0.65 Values: Range Minimum:''0.0'' is slowest, Maximum:''1.0'' is fastest.

Pitch controls the pitch of the voice. pitch=0.5 Values: Range Minimum:''0.0'' is lowest, Maximum:''1.0'' is highest.

A Pitch for capital letters can be set. capitalPitch=0.9 Values: Range Minimum:''0.0'' is lowest, Maximum:''1.0'' is highest.

The Volume controls the loudness of the voice. volume=1.0 Values: Range Minimum:''0.0'' is quietest, Maximum:''1.0'' is loudest.

Some speech drivers like speechdDriver can support various modules. these can be set here. module=espeak Values: Text, Consult speech-dispatcher's configuration to see what modules are available.

Voice selects the varient you want to use, for example, f5 will use the female voice #5 in Espeak, or if using the Espeak module in Speech-dispatcher.

Select the language you want Fenrir to use. language=english-us Values: Text, see your TTS synths documentation what is available.

Read new text as it occurs autoReadIncoming=True Values: on=''True'', off=''False''

  Generic Driver

The generic speech driver uses shell commands for speech synthisus.

''genericSpeechCommand'' defines the command that is executed for creating speech The following variables are substituted in ''genericSpeechCommand'':

•   ''FenrirText'' = is the text that should be spoken

•   ''fenrirModule'' = may be the speech module like used in speech-dispatcher, not every TTY needs this

•   ''fenrirLanguage'' = the language to speak in

•   ''fenrirVoice'' = is the current voice that should be used

•   ''fenrirVolume'' = is replaced with the current volume

•   ''fenrirPitch'' = is replaced with the current pitch

•   ''fenrirRate'' = is replaced with the current speed (speech rate)

Example genericSpeechCommand (default): genericSpeechCommand=espeak -a fenrirVolume -s fenrirRate -p fenrirPitch -v fenrirVoice "fenrirText"

These are the minimum and maximum values of the TTS system used in genericSpeechCommand. They are needed to calculate the abstract range in volume, rate and pitch 0.0 - 1.0.

    FenrirMinVolume=0
    fenrirMaxVolume=200
    fenrirMinPitch=0
    fenrirMaxPitch=99
    fenrirMinRate=80
    fenrirMaxRate=450

The current volume, pitch and rate is calculated like this value = min + [volume,pitch,rate] * (min - max ) ### Braille

  Scripting

Scripts can be in any language, bash, python, sh or others. Place your scripts in the directory /usr/share/fenrir/scripts/ (the path is configurable in settings.conf). The script key is the applications key. Usually this key can be found on the keyboard located just left of the right most control key. When you name a script, the key name appears in the script seperated by the sequence -. So, for example, if you have a python weather script you want assigned to the script key plus the letter w you would name the script /usr/share/fenrir/scripts/weather__-__key_w.py Then, to access the script, simply press the script key and the letter w. Scripts must be executable. So, make sure to chmod 755 your script when you place it in the scripts directory. The script gets some parameters from fenrir when it is executed. So that information is available in your script then.

  Parameterlist

Parameter | Content
$1 | Username of the current logged in user

  Examples

Script that just speaks the current username when pressing ScriptKey + H.\ File: ''/usr/share/fenrir/scripts/helloWorld__-__key_h.sh'': #!/bin/bash echo $1

  Commands

You can place your own commands in "/usr/share/fenrir/commands" (path is configurable in settings.conf). Commands are python files with a special scheme. You can assign them to a shortcut using the filename without an extension or place them in a hook trigger like OnInput or OnScreenChange. For further information see developer guide. Good Examples: "date.py" (https///github.com/chrys87/fenrir/blob/master/src/fenrir/commands/commands/date.py) (announce the Date), "shut_up.py" (https///github.com/chrys87/fenrir/blob/master/src/fenrir/commands/commands/shut_up.py) (interrupt output) the basic scheme for a command is as follows:

    from core import debug
    class command():
      def __init__(self):
          pass
      def initialize(self, environment):
          self.env = environment
      def shutdown(self):
          pass
      def getDescription(self):
          return _('No description found')
      def run(self):
          pass

•   Template lives here (https///github.com/chrys87/fenrir/blob/master/src/fenrir/commands/command_template.py)

•   The class needs to have the name "command".

•   "initialize" is running once whilst loading the command.

•   "shutdown" is running on unload like the command (quit fenrir)

•   "getDescriptsion" just returns an string. That String is used in Tutorial Mode.

•   "run" is executed when the command is invoked. (shortcut is pressed, or trigger isn't running)

•   setCAllback is currently not used. and has no functionality yet.

Troubleshooting

  Fenrir does not start

1.  Have you installed all the dependencies Support and Requirements (#Support%20and%20Requirements)

2.  Try using master, a lot of changes take place there to make Fenrir compatible with more systems ## Fenrir does not utilize the shortcuts

3.  Make sure you have python3-evdev installed

4.  Use the latest Fenrir version

5.  Make sure that Fenrir has permission to /dev/input/* and /dev/uinput (or run it as root) ## No sound at all

6.  Run the script to configure Pulseaudio once as root and once as your user. This will setup Pulseaudio but require a restart of Pulseaudio. The script is located in ''tools/configure_pulse.sh''

7.  Use ALSA

8.  Configure Pulse system wide (https///www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/SystemWide/) (Not recommended)

9.  Use gstreamerDriver: change ''settings.conf'' in the section ''sound'' the line ''driver=genericDriver'' to ''driver=gstreamerDriver''

10. Use wave sound-icons: change ''settings.conf'' in the section ''sound'' the line ''theme=default'' to ''theme=default-wav''

11. Use most current version of sox (http://sox.sourceforge.net/) with opus support

12. Try apulse (https///github.com/i-rinat/apulse) (not tested by myself but might work). Please give me feedback if you try it out. ## You get sound-icons but no speech

13. If you are using speech-dispatcher run "spd-conf" once as user and as root.

14. You can test if speech-dispatcher works by invoking it as root\ ''sudo spd-say "hello world"'' ## Bugreports and feature requests
