Set the default output sink. To list the output sinks available, type the following command: $ pacmd list-sinks | grep -e 'name:' -e 'index:' * index: 0 name: <alsa_output.pci-0000_04_01.0.analog-stereo> index: 1 name: <combined> The * in front of the index indicates the current default output.
command line - Get active sink in PulseAudio - Unix ...
https://unix.stackexchange.com/questions/547899/get-active-sink-in-pulseaudio
As PulseAudio (amazingly) doesn't provide any simple query commands, I'm parsing the output from pacmd list-sinks to get the index of the active sink. However, I'm not sure what lines actually indicate which sink is active. I know that the index line has an asterisk in front of it if it's the default sink. That doesn't appear to be the same as the active sink, though.

You either use indices or names but the former are not guaranteed to persist across sessions. You can get a list of both by issuing the command: pactl list sinks short. Try rebooting a few times and check what is the fallback sink each time. This can be done using GUIs like pavucontrol or from the command line. pacmd list-sinks | grep -e 'name:' -e 'index'
pulseaudio - pulse audio sink, what are they? - Ask Ubuntu

Pulseaudio has different volume levels for each sink. You can list those with: pactl list sinks | grep -e Name: -e Volume: But that isn't enough, because Pulse maintains a separate sink and a separate volume for each application. You can get a verbose list of running programs that are producing sound this way:
Look up pulseaudio sink-input index by property - Stack ...
https://stackoverflow.com/questions/39736580/look-up-pulseaudio-sink-input-index-by-property
Although it does parse the output and doesn't yet do any matching for the id you may be looking for, this method will provide a way, with some modifications, to get that information by sink id: pactl list sink-inputs | while read -r line ; do #echo "Processing ${line}" echo $line | grep -oP 'Sink Input #\K[^$]' echo $line | grep -oP 'application.process.id = "\K[^"]+' echo …

PulseAudio: Server Query and Control
https://freedesktop.org/software/pulseaudio/doxygen/introspect.html
Overview. Sometimes it is necessary to query and modify global settings in the server. For this, PulseAudio has the introspection API. It can list sinks, sources, samples and other aspects of the server. It can also modify the attributes of the server that will affect operations on a global level, and not just the application's context.
