Mute speakers when headset is plugged in

[rookieone]

Thank you, this is very usefull !

Below it showed that the range for 'headphone volume' is from 0-63, and for ' speaker volume' 0-31.

Code:

root@pinebook:/etc/acpi# amixer -c 1 sset 'headphone volume' 35
Simple mixer control 'headphone volume',0
 Capabilities: volume volume-joined
 Playback channels: Mono
 Capture channels: Mono
 Limits: 0 - 63
 Mono: 35 [56%]
root@pinebook:/etc/acpi# amixer -c 1 sset 'speaker volume' 35
Simple mixer control 'speaker volume',0
 Capabilities: volume volume-joined
 Playback channels: Mono
 Capture channels: Mono
 Limits: 0 - 31
 Mono: 31 [100%]

On my PB I've changed the values as below. Further I had to add the -c 1 option for selecting the right card.

Code:

#!/bin/bash

case "$1" in
   jack/headphone)
       case "$3" in
           plug)
               amixer -c 1 sset 'speaker volume' 0
               # amixer -D pulse sset Master 50% not working yet
               amixer -c 1 sset 'headphone volume' 35
           ;;
           unplug)
               amixer -c 1 sset 'headphone volume' 0
               # amixer -D pulse sset Master 50% not working yet
               amixer -c 1 sset 'speaker volume' 31
           ;;
       esac
   ;;
esac

p.s. I really recommend to NOT set 'headphone volume' to the maximum of 63, it will probably will be way to loud! (i tried till 51, too loud alread!
