Comment 15 for bug 108563

After searching some hours on the net, I find out the solution somewhere, you have only to unmute the mic booster, in alsamixer :
open a terminal,
type alsamixer or sudo alsomixer (if your not root)
and then go to "mic boos" and type "m" to unmute it : "00" should appear if it is unmuted
the press escape, and it should work better !!

I don't know why it is unmuted by default, I hope it will be in next version ! I found a lot of people wondering about that on the net, and only few sites giving the solution !

Good luck
