Did you get this worked out yet? VERY strange that you don't see pcm as a mixer control... It's a bit hard to say much with so little info but I'll offer a couple of things: 1) IMO Alsa has never run so well when drivers are compiled into the kernel. I do a lot of audio in Linux and have always had the best results using modules. I would strongly suggest you give it a try... 2) Under /proc/asound/card0 (or whatever card you are using if you have more than 1) do you see any pcm directories? 3) Post back a little more info? cat /proc/asound/cards aplay -l aplay -L lsmod Good luck, Mark
