ReplayGain for UPnP Renderer

[mminga]

Replaygain for UPnP user, possibly also working from alternative Apps, e.g. Bubble UPNP and HIFI Cast, when my reported bug can be solved.

Bubble UPNP and HIFI Cast not working

System Version: 3.324 Volumio Version: Hardware: Volumio Primo HIFI Edtion DAC: – Android 10 When playing on the system with both apps, after 2 or 3 songs, the playback stopps. It does not matter if the source is on my minimserver or local on my smartphone. As the volume keys at the smartphone cannot control the volume, I want to use the playback with the above mentioned apps. As it is a new system, I think to return it, if not working. I cannot find any help here regarding to it.

All files are tagged by replaygain-album and replaygain-track via foobar2000.
Bubble-UPP provides via ffmpeg-converter replay-gain: Off, Album or Track.
The developer of the App Hi-Fi-Cast mentioned, a renderer could read the tags coming from his App.

At GitHub I asked for a solution with gstreamer:

ReplayGain Support?

There is a solution, which could be used easily.
Virtual renderes could do it: Off, Album, Track
