[Issue]: No 5.1 audio with moonlight on Fire TV

[SchwingMC]

Some update: I tried a headless dummy in the hdmi port. The same issue appears. 5.1 sound stops after a while, stereo sound seems to work, with the exception of some cracking noises at the beginning of playback. So it seems that this issue is not caused by steam streaming speakers.
The internal Realtek soundcard has the same issue. It doesn't matter if audioplayback on host is enabled or not.

Resetting the fire cube to default settings hat no result, the issue still persists,

I also tried to use geforce experience, it had the same issue. So it seems to be no sunshine issue.

I also tested a different Streaming Box ( Strong Leap S3+ with Android 11) The Soundfail still persists. I'm using a yamaha TSR 400 as AV receiver.

So, i directly connected the PC to the AV receiver and this works flawless. So it indeed seems to be an Moonlight/Sunshine issue, everything else has been tested. It might also be Android, since I think Fire TV OS is also androind based.
