--- Comment #30 from Alojz Milicevic <alojz.milicevic at xmreality.se> ---
Can confirm 12.1.1 issues as reported by previous commentators. We are also looking for a solution to this and are eager for any news and help we can get!

I'm going to spend the next week on this issues and related issues, if any of you have ideas on something to try i am all ears! That being said here is what we have noticed so far:

 - If a tab has sound and we disable it by audioStream.enabled = false, the same tab can not regain it unless 
A. requesting and enabling video by calling videoStream.enabled. 
B. closing safari and opening it again (doesn't have to be a hard shutdown just switch to home screen and back).

(audioStream and videoStream are the streams we get from getUserMedia)

- If a tab/session/window does not have audio, there is nothing we have been able to do to gain it. Without first force quiting safari.

- When muting your sound, and switching video tracks. There seems to be no way of regaining your sound unless you also first enable the video track. 

This is what we have found so far. It is not bulletproof but will continue testing through this week at least.
