Bug Description

When using the experimental 5.1 surround sound, I semi-regularly hit a problem where sound cuts out on the stream entirely. This often coincides with a network hiccup (over wireless) where it mentions Unstable Network in the top right. However, sometimes it goes away when that message isn't shown, and I've also seen that message be shown where audio does not cut out. Suspending the stream and rejoining does not seem to fix it, so I usually quit the game+stream and just relaunch it.

I believe I have seen this since one of the first versions that added 5.1 surround. I do not remember ever seeing this without surround enabled, though I'm not positive this is true.

Is there any other information I can add to this bug report to make it easier to fix such as logging? I do not have a rooted device.

Reproduction Steps

1. Stream using 5.1 surround sound.
2. Have wireless network hiccup that is bad enough to mention Unstable Network in the top right.
3. Audio no longer comes through on the stream.

Expected Behavior

Audio continues to work.

Since there are new updates, would you like to try that first? Somehow I can't reproduce on my webOS 5 TV with 15% packet loss.

Can confirm it happens too on my TV: LG 55UN70006LA, WebOS 5.5
Connected via wifi. Audio cuts out after a few seconds or minutes of playing.

Not sure if it's connected to this issue, Sunshine with debug logs also prints out:

[2025:01:09:15:44:25]: Debug: type [Unknown] { 5502 }
---data---
01002801000E0006000F00060087768D765A080000
---end data---

around the same time the stream loses audio.

I recorded a video of it happening:

Hi @CraftWorksMC, do you experience it when you stream desktop too?

[CraftWorksMC]

Yes, it lasted a bit longer this time but it still cut out.

@CraftWorksMC What about stereo? Does it stop and you have to restart streaming?

[CraftWorksMC]

With it set to stereo, using the NDL-WebOS5 backend it works flawlessly, rarely the audio stutters a bit, probably because of the connection, but the sound continues to work. Uses the PCM-S16LE codec.
