But did you run '/etc/init.d/alsa start' as root? If so, and no errors
occurred, what does 'lsmod' (again, as root) return? -- do you see your
soundcard listed ("snd-cardname")?
It just isn't working on unstable, and I don't know why. I can load the various modules by hand--but /etc/init.d/alsa, although it gives no errors, loads no sound modules and unloads soundcore if it is already loaded.
