View Full Version : Optical Digital Out degrades on my receiver?

I am having a weird issue with my setup. I have a JVC RX8000V receiver, and
I've connected the SB to it through the optical digital out (haven't tried the
coax digital yet). When I leave them connected and powered up over night, it
seems to always get into a state where the receiver can't "understand" the PCM
stream anymore from the SB.

To fix the problem, I need only to power cycle the receiver. The SB is totally
fine. BUT... what I was wondering was could the SB be doing something non
standard to get the receiver into this confused state? Like when it goes to
standby mode does it output all 1's or just cut off the signal entirely and
this isn't a "nice" communication shutdown for my receiver?

Note these are just my own hairbrained theories. I know nothing about how the
optical digital signal works, or what the protocol is. Just wondering if
anyone out there has this problem, or knows of a solution.

Thanks!

Justin

Odd.

Next time it happens try unplugging/replugging the optical cable,
without power-cycling anything.

Also yes do try the coax connector as well.

Well, using the digital coax has completely eliminated the issue. For the
record, when I tried uplugging and replugging the optical digital cable while in
this state, it did not fix the issue. The only thing I found that fixed the
issue was power cycling the receiver. Note that I have little "L" and "R"
lights on the face of the receiver that tell me if it's getting data for those
channels. During this issue, those lights were not light up.

I think one other thing I should try (if I'm the curious type, which I am) is to
get it into this failure state, and unplug the SB optical, and plug in my
playstation optical and see if the receiver can recover then. I would assume
not, but maybe it would. Not even sure what that would mean though.

Anyway, just thought I would follow back up on this in case others have this
same receiver and want digital quality, they should be sure to use digital coax
and not the optical.

Thanks
