I recently purchased a RSB-11 soundbar. We've been very pleased with the audio quality and integration into our home theatre set up. I've noticed video latency, maybe a frame to 1.5 frames (33+ ms) to the audio. The video is behind the audio. I have an Xfinity cable box outputting audio and video via HDMI into the RSB-11 and then into our Sony TV. I have recently updated the firmware for the RSB-11 Has anyone else experienced this? Is there a way to fix this? Can delay be added to the audio signal to sync up with the delayed video signal? Any help is greatly appreciated JOHN
