Default Set alsa capture on using amixer

Hi,

I suddenly can't use my microphone for voice recording any more. I made
it work before. Now with the same HW and SW, nothing get recorded. (I can
hear the echo sound from the speaker when speaking to mic). Checking back
my log, I noticed one difference:

Previously it was:

$ amixer set Capture '100%'
Simple mixer control 'Capture',0
Capabilities: cvolume cswitch
Capture channels: Front Left - Front Right
Limits: Capture 0 - 15
Front Left: Capture 15 [100%] [22.50dB] [on]
Front Right: Capture 15 [100%] [22.50dB] [on]

Now, I can't turn the capture on:

$ amixer set Capture '100%' on
Simple mixer control 'Capture',0
Capabilities: cvolume cswitch
Capture channels: Front Left - Front Right
Limits: Capture 0 - 15
Front Left: Capture 15 [100%] [22.50dB] [off]
Front Right: Capture 15 [100%] [22.50dB] [off]
^^^^^

Any way to turn it on? I tried many, nothing worked.

PS. Here is my Mic setting:

$ amixer get Mic
Simple mixer control 'Mic',0
Capabilities: pvolume pvolume-joined pswitch pswitch-joined cswitch
cswitch-exclusive
Capture exclusive group: 0
Playback channels: Mono
Capture channels: Front Left - Front Right
Limits: Playback 0 - 31
Mono: Playback 31 [100%] [12.00dB] [on]
Front Left: Capture [on]
Front Right: Capture [on]

Does it look right?

Thanks

Can't say from your amixer output.
A bit of trial and error is the main way I solve this
problem... Would suggest fiddling with alsamixer
instead of amixer.
