Use a digital optical cable instead.
I have a sony sound bar - details above - which drops out continually and occasionally it will opt back in again without any input fron the remote control.
It reverts back to the tv sound which is poor in comparison.
Any suggestions why it drops out and back in again??
In addition - the remote seems to provide little or any control - it seems to go to standby and then some time later it will kick in???
Any suggestions would be most helpful.
