Sony a90j sound drop

[Gary65]

Looking for a little help please
Sony 65a90j sound keeps dropping when connected to soundbar , turn tv off and on and all okay again .
This is happening at least once a day , I have the same soundbar and Sony a8 before and no problems but since I bought the a90j nothing but problems.
Thanks Gary

Is it a sony soundbar by any chance Gary?

Thanks for your response and no ,Bose soundbar changed settings on sky q from Dolby plus to Dolby and no drip outs since .
