When playing 4K content through direct play (no transcoding or direct streaming), the audio plays for a minute or so, then completely cuts out and never returns.
Have tried with a variety of 4K content, last successfully played 4K movie was Sonic 3 back on the 22nd of January prior to the Dolby Vision 5 update.
Since that update, I’ve had the audio related issues.
If I play anything 1080p there are no issues.
My Apple TV outputs audio to a couple of Homepod Minis in stereo pair.
