Bluetooth Audio Delay/Audio Delay in General

Hey all,

I'm sure this topic may have been covered in the past, but I've searched some older threads and haven't had much luck.

I'm the first time owner of a TCL TV; picked up a 55 inch QM7.

I'm loving the TV so far, except the audio delay slider doesn't seem to do anything when it comes to a Bluetooth device that's connected to the TV.

Has anyone had any luck with this? Any workaround? Also, why is it I can back the audio sync to just -50, but can push it forward to a 1000 points or more on the slider? What is the logic behind that?

The audio sync out of the TV speakers seems to be fine when watching TV or movies, but when playing a gaming console, there is a slight delay. I've noticed this with both my Nintendo Switch and Xbox Series S.

Finding this very distracting and would love any help available! Thanks.
