Had this issue with the Motorola RNG-200N box as well. The solution from ComsastTeds worked, however still a slight drawback. I have an Apple TV (optical audio) along with the Comcast box both using Toslink optical into the HDTV for the digital pass through. It works great, but when I power everything off then turn the cable box back on, the audio is scrambled as if were picking up from both devices. If I switch the TV from HDMI cable to Apple TV input, then back to cable input, then the digital audio works properly on the cable box. Curious as to why?
