ALSA, on-board microphone not working (intel-hda) [SOLVED]

Staerseus · 2010-02-27 23:04:43

I have a trouble with my on-board microphone, it doesn't work for me. Second microphone, a jack, works fine but in KMix it is shown as "Capture" with an icon of an on-board mic... There is a second microphone "Digital" with a jack icon...

So I am confused of it...

I notice Capture is muted in your amixer output ('... [off]'). Do $(amixer set Capture on) to unmute it.

Thank you for you advice, the parameter "on" didn't help me, so I looked into the man pages and tried:

amixer set Capture cap

and it works now, thank you very much :-)
