Sound not working with ScreenCast

[appenzellois]

I can screen cast SoH from my phone to my android TV, but sound doesn't work, only video.

I think I can hear something on the TV for a split second, but then it mutes.

OP9 Pro android 12, XBox S controller on Bluetooth, TCL TV, Screen Cast over wifi.

Am I the only one?

Changing Audio Output Devices during gameplay messes up the audio output. Try first connecting to screencast, then running the game to see if that fixes it!

That doesn't work.
If I start screencast first, the casting is interrupted as soon as SoA starts.
