Previously, there have been several reports of broken surround audio on Netflix after updating the Apple TV to tvOS 14 and now, some users are also experiencing broken surround audio in Home Sharing following the update.
As pointed out by an iPhone in Canada reader, media files encoded with Dolby Digital 5.1 only play in stereo after updating to tvOS 14, regardless of whether they have a stereo track or not.
Moreover, some files that are encoded as Dolby Digital Plus (EC-3) seem to crash Apple TV altogether.
The issue seems to exist with all Dolby 5.1, 7.1, and Atmos content while using Home Sharing; streaming apps are unaffected:
“I still have a lot of media files that I stream and this is now severely broken. I have 4 Apple TV 4K’s and can’t even downgrade them to iOS 13.”
Updating the Apple TV to the latest tvOS 14.3 also doesn’t fix the issue. Apple has not yet acknowledged the issue but we are expecting the company to soon roll out a software update to resolve the bug.
Have you also noticed this issue with your Apple TV after updating to tvOS 14?
