I have Beam, two One’s and subwoofer along with Samsung NU6950 tv and PS4. The Beam is connected using HDMI ARC, the PS4 audio comes via HDMI to the tv. The tv is set up for HDMI Bitstream input and Dolby Digital output. The 5.1 sound is excellent but I’m getting about 1 second audio delay when using the PS4. I’ve read of others who have the same issue but don’t know if it has ever been resolved. Any guidance would be very much appreciated. Thank you.
