No Audio on Android TV

[charlie]

Hi, I recently set up Jellyfin on my Google TV and it was working fine for a few weeks but now I've encountered this issue. I'm not sure why as nothing has changed setup-wise, and I'm struggling to find a way to fix it. I've tried:
- switching the audio mode to 'downsample to stereo', testing and then switching back again.
- restarted the Google TV
- restarted the docker container on my server
- updated the docker container on my server

I can see from this thread that a fix was pushed out months ago, but my installation is much newer than that so I'm unsure how/why I'm still getting the issue.
Any help would be much appreciated, thanks
