Question

ARC on Pioneer and Panasonic

Hi all, a newbie here so please have patience with me Grin .
I've recently purchased and Panasonic TX-55FZ802B (OLED) tv and Pioneer LX701 AV amplifier.
All seems to work fine except when I try to run Netflix or Amazon from the TV via the ARC HDMI where I get the most incredible garbage of noise coming out. Via the pioneer app, I can see the input from the tv flitting between DD+ and unknown. I have tried several other hdmi cables with no change.
If I switch to PCM on the TV menu, then I get sound but only in two channel instead of 5.1.
I thought it was the amp so had that replaced but the issue remains so at a bit of a loss now.Could this be an incompatible issue between Pioneer and Panasonic?
Or do you think it is a problem with the tv?
Any advice would be much appreciated.
Thank you all

Re: ARC

Here's an old discussion about the subject: https://www.cnet.com/forums/discussions/no-netflix-5-1-audio-from-lg-tv-via-arc-or-optical/

It's quite confusing, and there seems to be no standard. If you dive into it probably Netflix will say it's a Panasonic issue (since they make the TV), and Panasonic will say it's a Netflix issue (since they make the app).

If this TV doesn't meet your requirements for sound, return it and buy one that does. Let the sales person in the shop show you that it works before closing the sale.

Let me be candid

ARC is a bust, and unnecessary. A simple digital optical cable connection between HDTV and AV receiver can provide very good DD 5.1 surround. Don’t be fooled by claims of DD+ or ATMOS sound that comes from a built in App. Frankly, most people don’t take time to learn how speaker placement works, so they miss 75% of what is possible with simple but effective 5.1.

If you need more details, feel free to ask but there are many posts with this stuff already.

So best to ignore ARC

First of all, thanks you both for your quick replies.
Secondly, judging by what I have been reading, ARC is brings more pain than benefit so just go with an optical cable. However, I understand that optical cannot carry Atmos (DD+ actually). I have a pretty sorted 5.1 system and my next phase is to expand into Atmos. I've already spoken with a local installer but if I'm going to miss out on a large chunk of what we watch then it makes me wonder whether I should proceed.

ATMOS isn’t the problem per se

It’s how you are doing it.

Start with a source outside the HDTV, not the built in Netflix app. Examples: Blu ray player or streamer box. This helps you avoid ARC headaches. DD+ is a ruse anyway. Have your installer position speakers in the room properly and calibrate the overall sound instead of worry too much about aTmos.

More info

Follow up.
So, just spent 90 minutes on live chat with Panasonic who tested the same model tv and the issue occurred with them too so it all seems to be a tv issue. They tried to say it was both Netflix and Amazon with the issue and not the tv but come on, both of them???
Anyway, they will be investigating further and hopefully will find the issue.
Thank you all for your help

Re: more info

Thanks for this new info.

Anyway, you'll have to wait for either a firmware update for your TV, or new versions of the Netflix and Amazon app to see this solved. Can take a long, long time.
