I've been trying to get ALSA to work on Gentoo for the past couple of days. I've got the modules to load, but I am still getting an error when I try to do anything. Amixer says "No such device" while mythtv reports "cannot open /dev/dsp". When I first installed /alsa, I had a symlink in place at /dev/dsp in a misguided attempt to fix what I assumed was a bug in mythtv (it's setup asks what audio device to use, but apparently only accepts /dev/dsp. I had compiled the kernel with support for the SB, which created a file /dev/dspW, so I linked the one to the other). I have since removed the symlink & replaced it using:
# mknod --mode=660 /dev/dsp c 14 3; chown root.audio /dev/dsp
but I still get the same error message

I am running Gentoo 1.4 rc1, alsa 0.9.0 RC6, with a SBLive.

goo alsa-lib # lsmod

Thanks!

You have to load a module for the sound card. snd-pcm and snd-mixer are not enough. Look at /lib/modules/`uname -r`/kernel/sound/pci/ for a module that looks appropriate, or just try executing

find /lib/modules/`uname -r`/kernel/sound/pci -name \*.o -exec modprobe {} \;

and try again. I am not sure how safe the latter is.
