I messed around with the settings a bit, but they seem to have no effect on the output of amixer. I read the amixer man page, and tried to set the volumes manually: jacob@jacob-laptop:~$ amixer -c 0 set 'Master' 100% Simple mixer control 'Master',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 31 [100%] [0.00dB] [on] Front Right: Playback 31 [100%] [0.00dB] [on] jacob@jacob-laptop:~$ amixer -c 0 set 'Master' 50% Simple mixer control 'Master',0 Capabilities: pvolume pswitch Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 16 [52%] [-22.50dB] [on] Front Right: Playback 16 [52%] [-22.50dB] [on] As you can see, changing the settings with amixer causes a change in the playback levels, but does not cause a change in "Simple mixer control 'Master',0". However, I just tested audio playback and it seems to be working again. Very strange. Thanks for your help.
