Help With Sound Issue - Pioneer Elite sc-81/Samsung F8500/Verizon Cable Box

I wasn't sure whether to put this in the HDTV section or here. It is technically a problem with the TV's speakers but the problem arose now that this receiver has replaced my Marantz sr-6005 that failed.

Okay so a quick summary of the problem. When I run all of my HDMIs into the receiver with 1 HDMI out to the TV, everything seems to work fine. (All HDMIS > sc-81 > f8500)


However, when I run an HDMI directly from the verizon fios box to the television, I get a constant high pitched sound on top of the TV audio with intermittent sound loss (All HDMIS except 1 > sc-81 > f8500) & (Verizon > f8500) Any ideas as to what is causing this? I'm trying to utilize ARC in this situation.


Troubleshooting Already Done
I've ruled out the HDMI cable, same thing happens with two other cables.
Ruled out problems with the HDMI ports on the f8500; I passed audio from my computer and the problem was non-existent.



Any ideas? This one has me stumped.

Update: (Setup currently: ALL HDMIS > receiver > tv) I turned on the TV and fios box this morning (receiver still off) and I had that same piercing sound. Soon after (Under a minute), I lost both picture and sound. So I turned on the receiver and found that it switched itself to the TV input (default channel for ARC) even though it was on standby; I didn't know it could do that while it was off (I have pass-through set to stay on the last input it was on). I turned it back to my Fios input and sound is fine out of the speakers. Turn off the receiver and sound is also fine through the TV.

Anyone know what is going on?

Problem is your Verizon box. You need to upgrade and get a better system. Dish network and the hopper

Haha couldn't resist. Good luck on your issue. No clue

Hahaha thanks.

Does anyone know if this is characteristic of a handshake issue?

I just fixed it by resetting the Fios box. I still don't know exactly what the issue was but I will assume that there was a problem somewhere in the box's settings.

Glad you got it working. For now. It doesn't sound like a handshaking issue, at least I've never experienced weird sounds. Most of the time, handshaking will give you either no sound, no video, or both.

Just in case, If it does end up being a hdmi handshaking issue, You might look into a gefen hdmi detective. I had all kinds of handshaking issues. I installed a gefen detective last night, and so far, so good.
