This will increase the volume by 2 decibels on the pcm channel. the argument to -c is for which sound card to use, the arg after set is the channel (PCM, Master, etc.) and what to set by. Related commands:
Adjusts the ‘Master’ channel’s volume up by 2dB
Can use command ‘amixer’ to see other channels:
simple mixer control ‘Master’,0
or
simple mixer control ‘Capture’,0
$ amixer -c 0 set PCM 2dB+Use to volume down
$ amixer -c 0 set PCM 2dB-Or
$ amixer sset PCM 10%-
$ amixer sset PCM 10%+
This will decrease volume by 2 decibels
$ amixer -c 0 set PCM toggle
To toggle mute/unmute
$ (amixer get Master | grep off > /dev/null && amixer -q set Master unmute) || amixer -q set Master muteThis is for alsa systems
Pulseaudio-ctl: vol+/- and mute from the shell or shortcut keys? :-)
This is much better then the amixer solution (amixer -D pulse sset Master 5%+), it lets me set the volume above 100% and with bad notebook speakers thats priceless
Glad you’re finding it useful. Enjoy! :)
