Can someone tell me why I don't have sound? I've followed the
instructions at http://www.gentoo.org/doc/en/alsa-guide.xml and
everything seems to be working, but there's still no sound. I've also
swapped out the speakers, made sure they were powered on, and the volume
turned up. Also I'm in the audio group and the channels are unmuted
with the volume at 75%.
One thing I did notice is that after running alsaconf there aren't any
modules in /etc/modules.d/, in fact the directory doesn't even exist.
Now if there aren't any modules to load that's fine, but since I don't
hear anything I'm not so sure.
Below is what's on my ~amd64 system.
Thanks.
