Hi there, I already read this article regarding this problem but I could not solve the problem:
My Denon AVC-X4700H (Amp with Airplay) is shown in the output list of the VOX Music Player but when selecting the device (also via the settings) there is no sound being played on this device.
When choosing another Airplay device (my old Airport Express connected to another amp) sound will play as expected.
Also when setting VOX Music Player output to “Same as System” and selecting the Denon Amp in the music output of the Mac the sound will play on the Denon.
MacBook Pro 15 2016
macOS Big Sur 11.2.2
Hope there is a solution or this can be fixed.
