Running mdv2008 I get very low volume from my VIA High Definition Audio
Controller. I have confirmed in kmix and aumix that sound is not muted
(alsamixer fails with the message "function snd_mixer_load failed:
Invalid argument"). I am using known good speakers plugged into the
correct soundcard jack, and I am attempting to play a known good audio
file.

I have tinkered with the sound settings in both KDE and Gnome, trying
different sound systems and hardware settings. One thing in particular I
tried in KDE is setting the sound system auto-suspend to 1 second.

I ran alsaconf as root.

Any ideas on what else I should be trying to get my volume up?

TIA,

FWIW...

I have a VIA chipset sound controller on my motherboard. I found a while
back that with my system, the remote speaker volume is controlled in
Kmix by a combination of the PCM and Headphone controls. Reduce either,
and the volume goes down. The others, including the Master, have no
effect. I have the PCM slider all the way up, and I control the volume
through the headphone slider.

Worth a shot, though YMMV. Hope this helps...

Interesting. My kmix has neither master nor PCM nor headphone controls.
Mine are line, microphone, pcm2 (but not pcm 1 or pcm), igain, and
digital1 -- same as aumix. Fooling with all of them has no effect I can
notice.

That IS interesting. Must have something to do with mine being
integrated to the motherboard, probably a different VIA chipset. Under
the output tab in KMix, I have sliders for Master, Master Mono,
Headphones, 3D Control-Center, 3D Control-Depth, PCM, PC Speaker, and
five labeled VIA DXS, whatever that is. The 3D and VIA DXS sliders don't
have little green dots, which I assume means they're inactive. Another
slider across the bottom is labeled VIA 8235, and seems to control the
right/left balance. (OT: Would that it were that simple with politics. A
nice, effective, simple right/left balance control. Sigh.) The only
place I see a "Line" or "Mic" slider is under the input tab.

Mine is on the motherboard too, so perhaps they are different chipsets?
My mobo documentation identifies mine as a VIA P4M890.

My mobo manual says the audio chip is VIA VT1612A. This is a
four-year-old computer, a custom-made job from a small company no longer
in business. The company called it an "entry-level" model then, but it
more than does the jobs I need it to do, even now.

Any chance kmix is picking the wrong device? At the top of the kmix mixer
window, the current mixer has a dropdown box to select the device. In my
case, I have a VIA 8237, or a USB Camera, which has it's own mike.

No, kmix only sees one device and so there is no dropdown box in my case.

I've been assuming you've read the Kmix Handbook, but I shouldn't have,
since I hadn't read it myself. I just had a look, and it's full of
interesting information. In case you haven't read it, try this: Right
click on one of the output sliders, then click on "Channels" in the
drop-down menu. Make sure all the boxes are checked. The ones that
aren't checked won't appear when you call Kmix.

Also, check to see that the green dot at the top of the slider is a
bright green. A dark green indicates it's disabled.

And yes, I see different sliders because I have a different chipset,
with different capabilities. Saw that in the handbook, too. Docs-
marvelous invention, those.
