This is happening consistently with my new 75 Q90A Neo QLED TV which is connected to a Vizio Atmos 5.1 Soundbar using HDMI Arc.
Whenever I try to play something on HBO Max, the audio stops working. I have to exit the video and start playing again and after 3-4 tries the audio usually starts working.
Anyone experiencing the same issue or knows how to fix it?
