When I record in high bitrate with TS format in 10 minutes block and download them to my computer, the sound is out of sync, sometimes by minutes. The TF card is a SanDisk High Endurance microSDXC Class 10 UHS-I U3 V30 256GB.
The GPS is also out of sync.
I also have problem with that the video stops and sounds continue.
Its a relatively fast computer with good margin in memory, processor and SSD disk.
Same problem with different video software as VLC, Dashcam Viewer and Lightworks.
