I have an issue with my sound as in I have a Sony ZF9 soundbar which was performing nicely then I got a output level drop and it is now barely louder than the tv alone, Richer Sounds have checked ZF9 any say it's working fine. Is there some kind of link in the TV that feeds a signal to the soundbar that can fail and still keep the TV working. I am HDMI cable from HDMI 2 arc to output on ZF9
TIA
