realtek bluetooth 4.2 does not connect with bluetooth headphones

Hello community,


Have any of you had trouble connecting your bluetooth headphones to your Realtek bluetooth 4.2 laptop?


I bought some bluetooth 5.0 headphones (Souncore Life Q20 model) and to make them work I had to use an old bluetooth driver, with the new ones it did not work.


I am using a Realtek bluetooth 4.2 v 1.6 driver (from 2019) to get my headphones working but I have a lag problem between the sound and the image of a video.


I have tried with other bluetooth headphones and connected them to the Realtek bluetooth 4.2 v 1.7 and there were no these sound challenge issues

Will anyone know how to fix this?
