GTMEDIA X1 soundtrack sync correction

[tag875]

I have been struggling with soundtrack sync issues when viewing my ATSC 3.0 channels. After months trying to investigate I found the problem and correction. This issues was not with any settings in my X1 but how I had my Audio settings on my Sony 4k TV. Since every TV is different all I can advise is use a good quality certified HDMI 2.1 cable between the X1 and your enhanced HDMI port on your TV and then adjust your Audio Output settings to turn on your A/V Sync. There are some additional sound settings on the X1 under Development Settings you can also test in Sound setting in Android 11.
