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.
Hi all, a newbie here so please have patience with me
.
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
