Description

Hi,

I'm currently on macOS Catalina, and I've installed this software from the release panel and not from homebrew.

Yesterday I've tried it using headphones, and it worked like a charm, then I've decided to use my AirPlay server so I can listen to music using external speakers, and suddenly it stop working.

I've chosen then, from System Preferences, to chose background audio as a default output device, but it doesn't work, I can't change the volume of Safari (yesterday I could), and from the menu, my AirPlay server is not listed.

Here it doesn't work (as I think it should)

Here it should work

But it doesn't and also the AirPlay server is not listed.

At least, choosing the AirPlay server as a default output audio device it doesn't work

But now the AirPlay server is shown, but if I choose Internal Speaker or Raspberrypi nothing changes (the audio still comes out from the raspberry)

So i was wondering, how? how can I make it work? am I doing something wrong?
