Another update. It seem all I need to do to get sound back is run |
| 38 |
alsaconf (take all the defaults) and reboot. I'm not sure why it stops |
| 39 |
working after two or three reboots, but if I run alsaconf again and |
| 40 |
reboot it's back. It never works right after alsaconf, it always needs |
| 41 |
a reboot. It would be nice if the sound state didn't get lost, but at |
| 42 |
least I can get it back. I'd also wouldn't mind knowing why it happens. |
