Microphone volume very low [duplicate]

I've installed Ubuntu, but the microphone volume level is very low (using Skype, for example).

It looks like the problem is only on the Settings page, because if I open "Pulse Audio Meter", it looks like it's working fine.

Could you check my attached screenshot?

Solution 1:

Your alsamixer settings show that the Mic is muted.

Open a terminal and issue the command: alsamixer

Use the arrow keys to highlight "Mic" which will be red.

Tap the M key and use the up and down arrow keys to adjust. (I would start at the midway point and adjust until I got the results I wanted).
