I have similar problem on my 2012 S80 ever since I had water ingress into my headlight, which fried the adaptive headlights module. Replaced adaptive headlight module but problem persists. If the sound is on and I turn off the engine, I can still listen to radio etc., but as soon as I start the engine again, I hear a pop and no sound from the infotainment, parking sensors etc.
Only solution is turn engine off, open driver door so car thinks completely off (infotainment turns off completely), close door and switch engine on for it to work normally.
Had Volvo look at it, run all the diagnostics, reinstall software etc. and no resolution. Have my own VIDA and couldn't find any faults or settings that would resolve.
Gremlins....
