I think you should select microphone as input source to make it work.
Excerpt from amixer output:
Code:
...
Simple mixer control 'Capture',0
Capabilities: cvolume cswitch
Capture channels: Front Left - Front Right
Limits: Capture 0 - 31
Front Left: Capture 31 [100%] [34.50dB] [on]
Front Right: Capture 31 [100%] [34.50dB] [on]
...
Simple mixer control 'Input Source',0
Capabilities: cenum
Items: 'Mic' 'Front Mic' 'Line' 'CD'
Item0: 'Mic'
You can do it in alsamixer (press F4 for record controls), KMix or manually (somehow, using amixer command).
And I recommend to use alsamixer/KMix instead of calling amixer directly.

run alsamixer, press F4, select your capture device with cursor keys, press "M" to unmute, or "Up arrow" to move volume up. Once device is enabled, run "alsactl store" as root to save (works on slackware).

It would be NICE if you posted which ways of enabling it you tried.
