Lenovo G50-30 mic built in volume problem

Question

my built in mic (the laptop is a lenovo g50-30) is too low and a bit distorted. I've tried it on skype and even in the audio settings the orange bars are pretty low. The mic is pre-amplificated above 100%. Any suggestions?

UPDATE: news here. I've tried a recording session with "arecord -D hw:0,0 -vv -f cd ~/test.wav" and it worked :D. So it seems that the problem is a skype problem?!?! Btw the optione "allow to skype to auto-adjust volume" is disabled. Update 2: i've tried the mic on my headphones. Skype works. I'm a bit confused now...

Solution

If the microphone is a stereo one, the signals from both channels cancle each other out and become close to a null value. If you disballance both channels slightly, you may get it to work properly.

No answer but I would just to confirm the "bug". Exactly the same situation on Lenovo G50-70 with Arch Linux.

Wow, great, this solved my problem. I was struggling with it for a week.
