Sound problems in PCCHIPS A13G+

Sound problems in PCCHIPS A13G+

[alsa-devel.20.pris]

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!

First, try the latest version (at best HG version or daily snapshot)
alsa-driver by yourself.  1.0.14 is fairly old for HD-audio.

If you still have the problem, try to pass model option to
snd-hda-intel, such as, model=3stack-660.  It's ALC660-VD as proc file
shows (which is almost compatible with ALC861VD aplay indicated).

Ok folks,

I have tried the following approaches without much success:
installing the latest ALSA driver from the repositories(this was
alsa-driver-hg20071129
at the time I did it.)

Then I uninstalled ALSA and installed the latest OSS driver. This
helped a bit and the sound was better, but still not perfect, I still
have problems with some AVI files.
So the last thing I'm trying now is installing the Realtek audio codecs:

http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=24&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false#High%20Definition%20Audio%20Codecs

So I downloaded it and followed the instructions. I managed to
successfully compile this driver but then when I run alsamixer I get
the following error message:

alsamixer: function snd_ctl_open failed for default: No such device

I read somewhere that this is due to some OSS modules still being
loaded and that I have to remove those OSS modules. So how do I do
that?

Thanks for any help!
If you need more information just ask.
