Ubuntu: Best way to set microphone volume by command line

Question

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

Try:

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 07 '10 at 12:57

With amixer you can set it with commandline

amixer scontrols gives you the controls you can set

amixer sset Mic 100% gives you the 100% of capture of your microphone

This works particularly well on Rasbian Lite, thanks. Also, if you look at the output of "amixer controls" you may see a range-- e.g. 0-35. For me "amixer sset Mic 100%" has the same effect as "amixer sset Mic 35". – BradChesney79 May 01 '19 at 03:04

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.

Adding to Sidjit Raput's answer which worked for me, you have to do:

amixer scontrols

... to find the ones to put in the volume setup/boost command (from bbs.archlinux.org > Alsa audio won't work). Mine was 'Internal Mic Boost',0 so:

amixer sset 'Internal Mic Boost',0 120
