Audio Problem with two Different Headsets

[thanku]

I have just upgrade my rom to

Schap's WM6 Pro

But I am having problem with bluetooth headsets

I get the audio drop outs ( Break) and it is choppy


I have tried it with two headsets Moto S9 and Sonny HBH-DS970

but it make no difference

I have also tried to change the bitpool setting from

31 to 97 and also tried the lower end like 14 but no improvement.

I be very grateful for any help

Regards
