ok one more time. Two TV's, two rooms, two audio receivers, one HD feed period. The only cable between the rooms is a HDMI cable. I wanted to use the digital out from the tV in the remote room to get a digital audio for the audio receiver in the far flung room as the 622 is 50 feet away. I can not move the 622 as it is feeding a TV in that room too. Yes I know we must watch the same HD program. That is not a problem as the two rooms are not usually in use at the same time. This causes me to ask if I SPLIT the toslink will it be a problem with a long toslink cable?
So just to be sure about your setup:
In one room, you have a TV, A/V receiver and the 622. All short connections. You are taking the 622's optical output to feed the A/V receiver in that room and (I assume) analog component video (or S-Video) to feed the TV.
You've run an HDMI cable to a second room with a TV and A/V receiver. The HDMI feeds the TV and you're taking optical audio out from the TV to that room's A/V receiver.
Correct or incorrect? If incorrect, please supply a drawing as I think we're just not getting how you've got things connected.
Now some questions:
Do you watch off air from the second room's TV (via antenna)? If so, do you get audio from the S/PDIF output for SD channels? (that would be PCM audio). Do you get S/PDIF audio on HD channels?
If you select the HDMI input (the 622 in the other room), you say you get audio from the S/PDIF output on the TV for HD satellite channels, but not for SD satellite channels? Or is it just SD locals via satellite????
You've double checked to see that there's no DD/PCM options in the TV that you're taking optical audio out of right?
If you watch any off-air TV via the second room TV's antenna, you'll need a path to the A/V receiver if you run a direct signal from the 622 to the A/V receiver.
As far as splitting and running long toslink cables:
Splitting the optical output optically will reduce your available signal and probably shorten maximum distance considerably. You may be able to find an active optical splitter or one that takes optical in and outputs optical and coax. You could then run S/PDIF over coax to the A/V receiver.
Most Toslink cables use plastic fiber and are not recommended for 50'. Look for a glass fiber and you should be OK.
Another approach would be to replace the A/V receiver in the second room with one that has at least one HDMI input that will extract the audio from that stream. Then you can run HDMI from the A/V receiver to the TV. Might be the least expensive and easiest method.
