Title:
Integration problems with pulseaudio and accessibility applications
Status in pulseaudio package in Ubuntu:
Expired
Bug description:
Binary package hint: pulseaudio
Dear Developers!
This is a long bugreport, sorry. :-):-)
In Ubuntu Karmic, I see lot of problems with pulseaudio:
First, before Karmic, pulseaudio is need disabling if the accessible profile
is choosed during installation, because impossible using accessibility
applications stable when pulseaudio is running.
Second, Ubuntu default gnome screen reader is Orca, and Orca knowns following
speech drivers:
1. Gnome-speech driver, (this is now not default with Ubuntu Karmic), need
installing with lignome-speech7 package with universe repository if anybody
would like use.
2. New default speech-dispatcher speech backend.
Now in ubuntu Karmic, if I choose accessibility profile, pulseaudio is
completely disabled by default, but now this is producing some problems:
1. Impossible to launch gnome-volume-control application, see this bugreport
link:
https://bugs.launchpad.net/bugs/439815
2. Impossible to use the hardware volume switch button, mute the volume and
increase or decrease volume values my Toshiba Satelite L300 notebook if
pulseaudio is not running, see this bugreport link:
https://bugs.launchpad.net/bugs/439822
I think my lot of problems related is pulseaudio/accessibility profile
integration problem. Why say I this?
If pulseaudio is disabled (if accessible profile choosed during
installation, pulseaudio is completely disabled), impossible to change
volume values, or impossible launch gnome-volume-control application.
But Orca screen reader works fine and stable if pulseaudio is disabled with
both drivers (gnome-speech driver and speech-dispatcher speech backend).
Why not I enabling pulseaudio again? Because:
1. If pulseaudio running and I try using gnome-speech driver, Orca cuts all
words and impossible understand the text (for example the screen have a dialog,
this dialog contains a settings button. Orca says se word only).
2. If pulseaudio is running and I using speech-dispatcher backend, very
slowest with speech-dispatcher/orca speeching, produced very big latencyes with
speech output parts (3 or 4 secs), this is very disturb, and result impossible
use the accessibility programs. For example:
The display present a dialog. The focus jump with the settings button. the
speech like following:
Settings (3 sec pause), button (3 sec pause), alts (this is the mnemonics and
3 sec pause again), the tutorial message and 3 sec pause with final. And this
is not long text. :-(:-(
But volume increase or decrease works if pulseaudio is running. What can I
choose, or how can fixing this
situation? :-):-)
I don't understand, why not setting the sound system with Alsa
automaticaly by default if pulseaudio is disabled. In Jaunty, I not see
this problems, this is Karmic specific situation.
Very interesting, but I try Debian Sid. Pulseaudio is not disturb the
accessibility programs, if pulseaudio is running, not disturb for
example the speech-dispatcher speech backend or gnome-speech driver.
If I removed pulseaudio my Debian Sid system, gnome-volume-control
starting correct.
Possible fix this problems, or have a suggestion?
