If you have a receiver with more than 1 HDMI input, use it but I believe the receiver needs to be on when watching cable TV. Use the hifi speakers
If not, there are HDMI switchers out there, someplace. Do a search.
Also, has anyone used Blue Jeans cables? Trying to sort through a myriad of info on how much to spend on cables, whether to use Optical or COAX for audio connections. You can spend a wide range on cables, and other forum threads seem to say it is not worth it. But is there a medium point where quality and consistency must count??
I may have their cable, not sure anymore
If your HDMI cable run is long, you need a good cable, with 22ga wire in them. I think Monoprice also has them for less though.
Optical or coax, not a problem, either are fine and equals. If you have a spare video cable use that as your digital audio cable, then it is free
Same cable.
