Microphone won't capture audio (ALC892)
 
I have openSUSE 12.2 KDE installed. Sound is working normally, but microphone is not. I tried everything, pavucontrol, alsa driver update, setting everything in kmix but nothing. My device is listed as Internal Audio Analog Stereo. When i try test.wav recording, it's just hear noise and nothing else.

My motherboard specs:

/usr/sbin/hwinfo --short

Code:

sound:
                      ATI SBx00 Azalia (Intel HDA)
                      nVidia Audio device

arecord -l

Code:

Been there, had this.

The hda intel is a jigsaw of 20 blocks, which you configure as someone else pleases.]
Manually edit /etc/asound.state, and see if you can spot the mike turned down, or off. Worth a shot. If not, post what it says about capture devices.

I have a Gigabyte F2A85X-D3H mobo with a ALC892 onboard soundcard on Debian Testing. It wasnt working well (kernel oopses etc) with kernel 3.2, it does with 3.6 and newer.

Other than that, run alsamixer in a terminal and check the input volumes etc there on the record tab (if you have pulseaudio running, press f6 and select the real card). Also, the lowest level sound capture test is (console):

Code:

arecord | aplay
or, high quality:
Code:

arecord -f cd | aplay -f cd
Stop with ctrl-c.
