I primarily use stereo HomePods with my 1st gen Apple TV. When watching 1080p SDR content however I find the audio is out of sync. Infuse is the only app that this happens. I have gone in and ran Wireless Audio Sync on 24fps and 23.976 1080p SDR but no success. I usually have to run audio delay at 80ms.
But this is the only app with the issue which is frustrating. Any thoughts or fixes?
