Re: [orca-list] [ANNOUNCE] libao (new audio driver for speechd including working pulseaudio support).

[Hammer Attila <hammera pickup hu>]

Dear List,

Halim, this driver is fantastic my machine.
I tested the new driver.
Before with this testing driver is publicated, Pulseaudio doing 2-3 
second latency when Speech-dispatcher is running in Ubuntu Karmic my 
notebook sound card and my desktop computer sound card.

I need remove Pulseaudio and coming back with alsa and do lot of 
workarounds to solving problems (volume increase/decrease workaround 
with custom keybinding command with amixer, remove unneed pulseaudio 
packages if I would like listen musics, videos etc).

Now when I testing the new driver, I am try the driver with Ubuntu Lucid 
system.

What can I see after when all required steps I doing the driver 
installation?
I get back my fast speech navigation when Pulseaudio is running my notebook.
Only a very minimal latency I see when I typing, but this is not matter 
(not 3 second latency). :-):-) Alsa is possible very little faster. But 
the new testing driver is very stable. Tomorrow I testing longest time.

What can I do when I would like compile and install the new driver?
Halim and me wroted 2 or 3 priwate letter, final, following simple 
method is working my machine. Note: Please, ewerybody try this method 
with only your risk!
Important, following method working with Karmic and Lucid only. Halim, 
if I any step writing incorrect, please complete. Excuse me my bad english:

1. In Lucid, I downloaded speech-dispatcher source code from following 
command with a directory:
sudo apt-get source speech-dispatcher

2. Please do following commands:
sudo apt-get install libao-dev (this is important)
sudo apt-get build-dep speech-dispatcher

3. I navigate the speech-dispatcher source directory.

4. Applyed the new patch:
patch -p1 <../speechd-libao.diff
Please replace the patch path if you storing Halim sent diff file with 
another place. :-):-)

5. I run dpkg-buildpackage command.

6. I installed with following packages with prewious directory (need do 
a sudo cd .. command):
speech-dispatcher, python-speechd, libspeechd2.
Possible your system needs another packages, but you found with 
rebuilded packages with your needs. Possible the version number is 
change with your system.

7. I change the /etc/libao.conf with default_driver=alsa to 
default_driver=pulse.

8. Final, reconfiguring speech-dispatcher with using libao audio output 
module. Don't worry, my machine spd-conf ask me the suggested way is 
Alsa, Pulse, Oss, but don't need correct your answer. :-):-)

Enjoy, the new driver working my machine.
