Get the audio sources

To get complete response

pacmd list-sinks

To get short response

pactl list short sinks

To set default output sink

pacmd set-default-sink "SINKNAME"

To set default Input

pacmd set-default-source "SOURCENAME"

To control volumn

pacmd set-sink-volume index volume

Volume control

Volume control values are

  • 65536 - 100%
  • 0 - mute

OR, bit more intuitive way to set proper volumn can be

  • 0x10000 - 100%
  • 0x7500 - 75%
  • 0x0 = 0%
pacmd set-source-volume index volume

Note: Changing the output sink through the command line interface can only take effect if stream target device reading is disabled. This can be done by editing the corresponding line in /etc/pulse/default.pa to:

load-module module-stream-restore restore_device=false

Restart pulseaudio for changes to take effect:

pulseaudio -k
