Control remote PulseAudio volume

Hi! I’m using the PulseAudio Loopback switch to connect a pulseaudio source to a sink on a remote raspberry pi (I have it connecting a record player preamp to a HifiBerry Amp2).

Does anyone know of a way I could control the pulseaudio source or sink volume from Home Assistant? Perhaps via a third party addon or somehow using the audio plugin which has pulse running?

I am currently looking for the same. I used this integration 4 years ago before I moved.

I just got it set up again today for my whole home audio solution. This is next on my list to find a way to control each sink volume.

Note if you are using MPD as a source then you can control that out of the box with the MPD integration. But I’d rather control each room’s (sink) volume separately.
