Add new AirPlay device - Unknown error occurred

[Cervenka]

Hello,
I just installed this add-on via HACS. I upgraded miniaudio as suggested.

However when trying to add the integration I get prompted if I want to auto-add devices. If I click no the integration does not show up. I click yes following error shows:

Add new AirPlay device - Unknown error occurred

Is there a suggested fix for this?
Thank you!

Just set up a new HassOS staging VM to test our some stuff, including this integration but do encounter the same error message while setting it up:
Here is a log for a little more context than 'unknown error'

This error originated from a custom integration.

I started getting this error after installing the "Apple TV beta" integration. Do you have this installed?
