I have tried sharing logs under renctan. Some songs cannot play to my Marantz. I don’t know what is it yet because it’s not just file format, but always the same set of files. Sympfonium have no problem playing locally. I can cast the same song via subsonic when using bubbleupnp
When I select it to play locally (note: I didn’t include the local device in the media provider, subsonic is the only provider), the end time is displayed correctly with “speed 1x”
I couldn’t find the renderer settings and the proxy option you mentioned. I’m using the Android app version 13.5.0b.
I think I noticed the pattern, most of the time, it appears to manifest only on the last song of the album. And in my original example, I only bought a single song from the album so it also happens to be the only and “last” song of that album. It doesn’t appear to matter if it’s mp3, flac or aac.
