Alsamixer doesn'i show muted input. Not does gnome-volume-settings. I
also checked out gnome-sound-properties, and it gives no errors at all,
as if it thinks everything is working fine.
Here is the output from amixer:
Simple mixer control 'Master',0
Capabilities: pvolume
Playback channels: Front Left - Front Right
Limits: Playback 0 - 42
Mono:
Front Left: Playback 34 [81%] [-12.00dB]
Front Right: Playback 34 [81%] [-12.00dB]
Simple mixer control 'PCM',0
Capabilities: pvolume
Playback channels: Front Left - Front Right
Limits: Playback 0 - 255
Mono:
Front Left: Playback 255 [100%] [0.00dB]
Front Right: Playback 255 [100%] [0.00dB]
Simple mixer control 'Capture',0

Capture channels: Front Left - Front Right
Limits: Capture 0 - 31
Front Left: Capture 20 [65%] [13.50dB] [on]
Front Right: Capture 20 [65%] [13.50dB] [on]
and here is /proc/asound/cards
0 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xf9ef8000 irq 22
I'm going to try a LiveCD or such, but I'm not very optimistic.
Thanks anyway.
