Bluetooth output lagging

[hysteresis]

Hello
I have a problem with a bluetooth output on Amp and Amp Pro. The sound comes with a delay compared to picture. I have LG CX and an old sony tv. LG has a bluetooth output for sound, and it doesn’t have a delay.
Amp/Amp Pro is connected to HDMI-Arc. Analog output doesn’t have a delay.
Any solutions for that?

Did you check your audio settings on your tv to make sure it was stereo instead of Dolby digital? That causes 600ms delay on my wiim amp pro
