When watching sky sports on my apple tv 4k or apple tv 1080p I have the sound coming out of a homepod, (the issue occurs on hompod mini and the big one), as soon as the adverts comes on the sound cuts out and wont come back until you come out of the app and go back in even when the program resumes after the adverts.
I have a similar issue when watching Sky Sports using the Now app on my Apple TV 4K with a Sonos Beam and two Sonos One’s. Pretty annoying at the start and end of every single ad break that the sound settings need to be messed around with. As per previous posters this doesn’t happen on any other apps.
Same issue. What is odd is when audio output is set for TV speakers all is good. When audio is the HomePods the issue occurs. Is this a NOW TV issue or Apple!? On basis it doesn’t happen watching live TV on other apps I’m guessing it’s a NOW TV app issue.
