hi , can somebody help me with this. I have Tcl roku tv 50" and sony hts350 soundbar+wireless sub .the thing i used to do, is my soundbar volume is always maximum. so i dont need to keep volume high for my tv like 20 was enough i never cross 30-40 beacuse soo loud. now the thing is happening both volume r linked dont know why . either tv remote can control both device volume or even soundbar remote can also do the same . So the question is how i can unlink or something like because i know it was not same before......
