I'd like to set audio balance from command line (linux), I'v looked at 'aumix' (and googled around) but it seems it does not have an option... can you suggest any method?

    `alsamixer` gives GUI in terminal, but it is not probably what you want –  Jul 31 '11 at 09:24

With amixer, you can set the volumes of the left and right ALSA channels. For example,

amixer sset Master 80%,20%

will shift the balance toward the left.

  • what's the difference between `set` and `sset`, and `get` and `sget`? The help doesn't mention it. – Torben Gundtofte-Bruun Feb 14 '16 at 09:03

    A look into the source code shows there is no difference on modern versions of alsa-utils. `set` and `get` where introduced in commit c569788bf207a0aa6e4a475e36062a3546b689bb, for compatibility with a mixer API. So both work fine. – phihag Feb 14 '16 at 20:57

    With pulseaudio: `amixer -D pulse set Master 80%,20%`. – Pablo A Mar 15 '19 at 04:31

If you are using MacOS you create an AppleScript:

# Start preferences with the right page
tell application "System Preferences"
    activate
    reveal anchor "output" of pane id "com.apple.preference.sound"
    delay 0.5 -- If you get an error, it's possible this delay isn't long enough.
end tell
# Set volume balance to normal
tell application "System Events"
    tell slider 1 of group 1 of tab group 1 of window 1 of process "System Preferences"
        set value to 0.2
    end tell
end tell
# Quit system preferences
tell application "System Preferences"
     quit
end tell

I searched everywhere for this answer and here what I got

  1. Download Alsamixer.
  2. Go to settings and select "alsa_amixer controls" or the second option under the mode
  3. From all commands search for "Headphone Volume" and change the values to 63,0 or 0,63.
