Sceptre Tv into Roku Sound Bar Tv audio breaking up
Hooked up a new Roku sound bar to my Sceptre TV. The input to the tv is from my cable box....into HDMI 1 the connection from the Tv to soundbar is HDMI 4 (arc) I am getting the sound cutting in and out from tv channels. Everything is fine when watching from the Roku itself. Netflix, Disney+ etc. Just happening while watching cable. Any suggestions?
