Using Glider to control a DLNA server (MinimServer) and render to my AVR, volume is ineffective.
After setting the AVR as the device, the graphical slider in the player is all the way down and the AVR volume is 0. Moving the app slider results in it snapping back to 0.
Setting the volume via AVR controls results in the app slider either pinning left or right. (It’s pinned at max when I set my AVR volume about 1/3 up).
Rocker volume controls on my iPhone bring up the OS volume overlay, which doesn’t seem to track (or control).
Playback works - just have to set the volume on the AVR.
This may have been introduced with 2.0, as it used to work.
