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.
