I have tried:

aumix -i 100

However that only seems to get me to about 3/4 of the maximum volume when I look at the change in the Sound Preferences panel.

Here is a screenshot of Sound Preferences panel with unexpected microphone volume:

I am using Xubuntu 9.10.

Just found out that using alsactl store to save audio settings could help! – Luke Stanley Sep 15 '14 at 12:16


amixer set Capture 5%+
amixer set Capture 5%-

to increase or decrease the mic volume.

hmm thanks. This has the same issue though. It caps out at what it says is 21dB. – Luke Stanley Jul 7 '10 at 12:57

You could try alsamixer. It's a simple CLI mixer for Alsa.

amixer sset 'Digital',0 120

This is just an example. Replace 'Digital,0' appropriately. 120 is the mic level.
