Can you answer these questions:
With Volume keys
setting enabled and mopidy the active renderer in BubbleUPnP:
- in the current
update version (3.8) are you able to control mopidy volume with hardware buttons when the app is in the foreground
- in the previous
version, were you also able to control mopidy volume with hardware buttons when the app was in the background,
and that's what is not working anymore with the current version ?
Volume control is kind of complicated depending on Android versions and devices and other factors, so please answer these precisely. You can optionally restate in which circumstances hardware volume control is not working in the new version (not at all all, only when app is in the background, ...) while it was in the previous version (but please answer above questions first!).
