It turned out to be some odd quirk with my particular sound device (via82xx). I started out with NO sound at all. Here's the things that finally got mine working: 1. I updated the kernel, and sound started working--barely. I had to have the physical volume control turned all the way up to 11 to get a whisper out. 2. There are apparently quirks with many sound cards that the drivers can compensate for ... but how to find out if yours qualifies, I have no clue. Maybe the source? It turned out that the only volume control that worked was the headphone level--not the master control (which is a pain when you want to mute and have to bring up a full mixer). I had to add "options snd-via82xx dxs_support=4 ac97_quirk=1" to my /etc/modprobe.conf. Now I could control the sound via the master control. 3. However, there were still other mixer controls that had an effect. I had to scroll over to the far right on alsamixer and kmix, where there are four more sliders labelled VIA DXS. I have no clue what they're for, but I have to crank the first one up. I realize you have a different sound chip, but maybe all this will help you at least look at other solutions.
