Samstag, 19. Dezember 2009How I solved my Ubuntu Karmic 9.10 ALSA OpenAL Sound problemsI was suffering from a soundproblem on my fresh Ubuntu Karmic installation. All programs using OpenAL would stop playing sound and start to play scratchy sounds until sound drops completely out. Plus those programs will hang when trying to shut them down. For example OpenArena and Warzone2100 are affected which comes really hard to me I tried a lot of different things with little success. Most solutions only helped for a moment until the problems came back. I think it's just that it works a little while after a reboot. Basically I don't know what really fixed the problem, but these changes here are in efffect right now and work for me.

I solved them without package installations (on Ubuntu 9.10 32-bit):
Just added drivers=oss to /etc/openal/alsoft.conf Sound is fast and correct again.
I tried that, too, but it didn't help me with any OpenAL programs. Tested with OpenArena and Warzone2100. You sure it works for you?
Hello Jan Girlich,
I've got the same problems. For me it's X-Plane and FlightGear... I've tried all the descriped steps and still got the problem. So the "HDA Chipset Tweaks" would be of interest for me! For your notice: I had to type sudo add-apt-repository ppa:stesind/stesind-alsa-21 instead of sudo add-apt-repository ppa:stesind-alsa-21. I'd be very pleased if you could descripe your "HDA Tweaks" for me... Best regards, Lucas Sichardt
I added this line to /etc/modprobe.d/alsa-base.conf
options snd-hda-intel model=thinkpad I also tried out a lot of different other settings with no measurable effect. options snd-hda-intel model=3stack-6ch options snd-hda-intel model=3stack-6ch-dig options snd-hda-intel enable=1 index=0 model=3stack-6choptions snd-hda-intel model=auto probe_mask=1 Have a look at these pages, those were my ressources: https://help.ubuntu.com/community/HdaIntelSoundHowto http://www.kernel.org/pub/linux/kernel/people/tiwai/docs/HD-Audio.html HTH Jan
Thanks Jan for this Info in such a short time - now I know what you meant with "HDA Tweaks".
But this is what I tried more than one time yet. So as you mentioned originally this seems not to be the solution - what a pity... Best regards, Lucas |
