Description of problem:
I have a laptop which has a VIA Tech sound chip. The Chip is
identified as "VT8233/A/8235/8237 AC Audio Controller" in
/etc/sysconfig/hwconfig. The snd-via82xx module is being used for this
When I play .ogg files through winamp, rythmbox, or ogg123, I get
sound that is low volume and has a lot of static. I get the same
results when I use playwave to play a .wav file. I believe this issue
is caused by not having a volume control for the "PCM" input. I have
used the gnome volume control panel, kmix, alsamixer, and aumix, but
cannot control the volume to PCM, only mute it. I have come to this
conclusion after playing DVDs. I had the exact same issue with DVD
audio until I located the second "VIA DXS" slider (there are a total
of 4 sliders with this label) and increased it considerably (A little
over half way). I might mention that on FC1, and FC2, I did not have
this issue. On none of the 3 FC releases have the "Master" volume
control worked. I typically set the input control fairly high, then
use the volume control wheel on the front of my laptop to adjust the
volume to my headphones (or crappy built in speakers). I do not know
whether the master volume control works on Windows as I do not use
this laptop for windows. I've always assumed that the chip does not
support it because of the manual volumn control wheel.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install Fedora Core 3 - 32 bit on Mitac 8335 laptop (maybe others)
2. Try to adjust the PCM volume control (you can't)
3. Try playing an ogg file with either xmms, rythmbox, or ogg123; or
try playing a wave file with playwave.
Actual Results: Low volume sound with lots of static.
Expected Results: Normal volume sound with no static.
This is a Mitac Model 8335 notebook. This notebook has an AMD 64 bit
