upnp: missing plugin

[tmigone]

Describe the problem

The app finds my balena-sound host but when I press Play, there is no sound and the Play button does not change to Pause (as it does when I choose the 'local renderer')...

Hi @tmigone! Thanks for helping! Here is similar issue I've found: #342 and #405

It also kinda suggests a solution (moving to newer version(v0.0.9) of gmrenderer and potentially to gmrenderer-resurrect), which worked for me (please read there)

[drew1kun]

basically after updating FROM stanza at plugins/upnp/Dockerfile.template as follows:

FROM balenalib/%%BALENA_MACHINE_NAME%%-debian:bullseye

and rebuilding the project from scratch, the issue is gone, but the stability of the UPnP sound quality is still poor: the music often sticks, stops etc...

The content I try is audio, shared from my Youtube Music app on Android... But for that to be played, I enable "FFmpeg audio decoding for Audio formats not natively supported by renderer" in my Android BubbleUPnP app for my balena-sound render.
