Microphone not working, or too quiet [Solved]

[erthalion]

Hi everyone! I have a fresh installed Gentoo, but there is a strange problem with microphone - there is no any captured audio nor from arecord, nor from skype-4.3. Sometimes (and I don't know, what I've changed for this) audio can be captured, but it's to noisy and quiet.

Here is information about hardware:

In alsamixer hit F4 and try to enable/increase Mic Boost. Also play with Capture. Normally, it should be enabled (Hit Space when control is selected).

One more thing to check is the tweaks for snd_hda_intel. Read /usr/src/linux/Documentation/sound/alsa/HD-Audio.txt to see if there's anything useful for you.

Though, you should also check your microphone under Windows. I had once a laptop, where microphone was simply bad and didn't want to work with any settings. It did capture sounds, but those were very noisy and low.

v_andal, thanks for the reply. I found the source of problem, and the next time I should look at the "amixer" output more carefully)
