I have installed Auromasters on my Sony A95K (Google TV) and it plays me in stereo and I have it configured with Auro 9.1 to take it out on a Yamaha A8A (Auro Native). I have written to them.
I was a Dell Inspiron 15 5510 with HDMI a Yamaha A8A
I tried logging onto the stream from 6:10 to 6:50. Only saw a screen of Artist Connection. No sound.
On mobile (Oppo), I did get video and audio with Sony headphones (WF-1000XM5).
