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. |

Thanks. |
