AppleTV 4K sound sync issues with sound bar
Anyone ever have any issues with the sound being out of sync when using a sound bar with an AppleTV 4K?
Issue: When sound settings on Apple TV are set to Auto (it'll select the audio based on the source, 5.1, etc), the sound is out of sync on my sound bar. Changing the ATV4K sound option to "stereo" and then using the "bypass" feature on the OLED will fix any sound syncing issues, but you're only getting down mixed stereo. Basically anything that's not stereo coming form the Apple TV is out of sync when using a sound bar. I am connected with HDMI-ARC and have connected and had this issue since day one.
However, when using the internal OLED speakers and the sound set to AUTO on the ATV4K, there is no sound syncing issues. If you then change/select the option on the OLED to use the sound bar. it instantly makes the sound not match up with the video. I've now tried two different sound bars using the same settings and both sound bars have noticeably out of sync sound (one was a Samsung and another a Sony). I've tried changing multiple settings on the TV, using the bypass feature, changing from auto to PCM. Nothing fixes it. If I switch the APTV4K to stereo output only and then utilize the bypass feature, sound is completely fine. There is also an audio sync feature on my sound bar - that didn't fix anything.
Anyone else have similar issues?
edited to add: a quick google search reveals that people have been having similar problems since the original AppleTV...and all of the other forum posts are people with OLEDS having the issue.
