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).
