pacmd "failed to set sink port" when trying to change which output on my sound card to use
Solution 1:
From output of your list-sinks
we can see that by default your headphone sink has index 1
, your speakers sink has index 2
(HDMI is 0
). Provided you have a default setup for PulseAudio you should be able to switch between these two sinks by issuing:
pacmd set-default-sink 1 # for headphones
pacmd set-default-sink 2 # for speakers
See also this answer for changing sink output while an active stream is playing and how to disable stream device restore.
Solution 2:
Surrounding the port name by quotes("..."
) worked for me. So try
pacmd set-sink-port 2 "analog-output;output-headphones-1"
