Subject: [gentoo-user] ALSA - No Sound

1 Can someone tell me why I don't have sound? I've followed the
2 instructions at http://www.gentoo.org/doc/en/alsa-guide.xml and
3 everything seems to be working, but there's still no sound. I've also
4 swapped out the speakers, made sure they were powered on, and the volume
5 turned up. Also I'm in the audio group and the channels are unmuted
6 with the volume at 75%.
7
8 One thing I did notice is that after running alsaconf there aren't any
9 modules in /etc/modules.d/, in fact the directory doesn't even exist.
10 Now if there aren't any modules to load that's fine, but since I don't
11 hear anything I'm not so sure.
12
13 Below is what's on my ~amd64 system.

15 Thanks.
