On Windows my microphone works, but not on GNU/Linux distributions. Have I done anything wrong? I use audacity to test it. sysdefault: Rear Mic: 0 is selected as the recording device, Channels: 1(Mono). I also tried it with Skype, but it doesn't work either (default device selected in options).
Architecture: 64 bit
Card: HDA Intel
Chip: Realtek ALC888
alsamixer capture configuration (http://pastebin.com/KpKBhrKi)
Rear mic is all the way down. Have you turned it up?
Sometimes there is another one that needs to be turned up for mic,
like master, pcm, mic gain etc.
F5 while looking at alsamixer and use the left and right arrows to see them all.
Unmute everything and turn them up.
Some sound devices need a virtual loopback device to record a sound and hear it at the same time.
Find your microphone device and something like
ffmpeg -f alsa -i hw:0,0 -c:a copy -vn out.wav
should capture your mic input. Or audacity, or sox.
arecord -vv -fdat out.wav
you should see the + sign moving as you speak in to the mic.
Look at man amixer and man arecord
There are also several recent threads on this forum about getting mic to work.

Ok. I turned rear mic up. master, pcm and mic boost are also turned up to max. I already read most of these links.. nothing worked.
here my new config: http://pastebin.mozilla.org/3156878
Item: Rear Mic [dB gain: -34.50, -34.50]
That's all the way down. I can't tell what you have by that pic.
Won't that mic mixer control turn up?
How do you know? What did you try to do? Did you try to record to file? Or are you trying to hear your voice through your speakers? Did you make a virtual loopback device and try the inputs for the right one?
What is the output of
Use that to find the correct hardware device like for example hw:0,0 hw:0,1
After you've found the correct hardware device, try to record to file.
You may need to make a virtual loopback device, in the last link I posted. A machine I have, which has a nvidia sound device, will not grab the mic without a virtual loopback.
"Item: Rear Mic" is just an item that makes noises (even if I am not even recording something). Doesn't really help. By not working I mean that this "ffmpeg -f alsa -i hw:0,0 -c:a copy -vn out.wav" doesn't record anything.
The output of "aplay -l" is: http://pastebin.com/FUgjgvt5
hw:0,0 seems to be the only hardware device.
anyone knows a solution? thanks.
