I have a Time Warner Cable Box, Blu Ray Player, and Wii all connected to my Denon 791 receiver. The cable box and blu-ray are hooked up with HDMI cables, and the Wii with a component. One HDMI goes from the AVR to the TV.


Everything works fine, except that on some cable channels, the audio cuts in and out. I looked this problem up on the forum, and read that it might be an issue with the HDMI cable.


I have had this problem with the 3 cable boxes I've had in the last year - all using the same set up. I've tried setting the cable box to "HDMI," "Dolby Digital" and "Other" The channels I have this problem with are working fine for the next door neighbor.


I ordered an optical cable from monoprice, and while waiting, I hooked up the cable box to the AVR with an analog cable. I changed the cable box audio to "Other" and the AVR input to "analog" and the sound problem was fixed. But the AVR put out audio as "Stereo"


When I got the optical cable, I hooked that up, and changed the cable box to "Dolby Digital". I set the AVR input under CAB/SAT as "O1", and input mode as "Digital" with decode "Auto" - But I had the same problem I had with the HDMI cable. Any suggestions?

This is likely an HDMI handshake issue with the cable box, quite common with many cable/sat boxes. Connect the HDMI from the box to the TV with optical from the box to the AVR for surround audio.

Unfortunately, this did not work. The HDMI from cable is going to the TV, and the optical is going to the AVR. But I am having the same exact problem, and I don't have this problem with the analog cable.


Are there any other solutions? Otherwise, I will keep everything connected to the AVR and use the analog audio.

As you note, the issue is only with those particular shows. Unless you have an HD box, the SD channels only broadcast in stereo anyway, so no loss in quality using the analog audio cables.

I do have an HD box. I'm sort of curious as to why this is happening. It just seems like a strange problem.

May be time to change to other than a Time Warner box.

lol. i'll stick with the analog for now I guess. i can always change the input mode to HDMI through the receiver if I need it.


thanks for taking the time to help me out.

One more thing to check if the cable box as an "orange" digital coax out jack is to connect a "yellow" composite video cable from there to a coax digital input on the AVR.
