I want to be able to watch cable tv with or with surround sound. currently the cable box is connected to the tv with hdmi. I do not have the receiver connected to tv yet. Thanks
You should be able to hook the cable box to your receiver with the digital (optical or coax) connection. You can't use HDMI since the 605 will not pass the sound through.
sflamedic............. The easiest way will be to run the red & white RCA audio cables from the cable box to the tv for audio, and maybe component cables from cable box to tv, for video. Then you can watch and listen to tv, even HD channels, without the surround system being on.
