I want to activate a microphone on my machine via the command line. I use amixer for this.

amixer set "Front Mic" 66%
amixer set "Digital" 100%
amixer set "Front Mic Boost" 100%
amixer set "Capture" 100%

This set the volume settings. The problem is that capture is deactivated. Amixer displays this output:

Simple mixer control 'Capture',0 Capabilities: cvolume cswitch Capture channels: Front Left - Front Right Limits: Capture 0 - 54 Front Left: Capture 27 [50%] [-18.00dB] [off] Front Right: Capture 27 [50%] [-18.00dB] [off]

I can active capture via kmix after that amixer shows the channels as on. But the man pages don't show how to activate the channels via amixer.
