I just recently got the Bar 48. I have the HDMI (Arc) from my TV going into the soundbar. Numerous times the audio would just go out, and I'd have to fiddle around with the inputs on the remote to get the sound back. I'm not sure why this is happening. When I switched to the optical cable, everything seems fine, but then I lose the benefits of the HDMI Arc. Has anyone encountered this issue?
