My motherboard: PCCHIPS A13G+
http://www.pcchips.com.tw/PCCWebSite...uID=44&LanID=0
I'm using Ubuntu 7.10 - the Gutsy Gibbon, I was using Feisty before
and had the same problems.
The interesting thing: the system sounds all work. Some example .ogg
files that came with Ubuntu also work.
There is one example file however "fables_01_01_aesop.spx" which only
gives a very low sound, almost inaudible.
The real strange thing happens with ".avi" and mp3 files. They sound
distorted and very low, almost inaudible. Some have better/louder
sound, but still distorted, but I can understand what is being spoken,
others not.
Thanks for any help!
If you need more information just ask.
Technical details follow(including the Alsa Audio Debug):
