If you're still having this issue you might want to try changing the HDMI Audio Format to "Pass Through" that's the equivalent of bitstream so it should send the audio as intended to a soundbar/AVR. Also it might be worth changing the "HDMI auto setting" to mode 2 in the setup menu. That drops the HDMI port back to HDMI 2.0 instead of 2.1 meaning you lose the gaming features e.g. VRR, 4k120fps but it seemed to fix my audio issues.Sorry I don't understand what you mean by switching back to HDMI2? I only have one HDMI cable from my AV amp to the TV. Do you have two?
Have you tried launching Netflix from the AV input, instead of hdmi 1 to 4, as this usually fixes the issues until I turn the tv ooff and in again.
Have been watching Disney all day with the little one, have watched Netflix for a couple of hours last night.
It does only happen occasionally…but it should not happen at all!! I have a Sonos Beam 2 which is compatible and it comes with the relevant HDMI cable, tried switching to the QED cables mentioned and still no change.Fingers crossed your situation doesn't change! If it does, be sure to report back ..
Happened again yesterday. Only way to stop it was to turn the tv off at the mains and back on again!I’ve got the same issue. Beam 2 connected to HDMI2. Sound either cuts out for 5 seconds or so or the sound is really glitchy. Not all the time. Very random and happens on both TV and any other connected device.
No, not yet. I was trying to see if there was a pattern before reporting to Panasonic but unfortunately and annoyingly it's very random. I've tried with and without the soundbar (Sonos Beam Gen 2) connected (HDMI2) but still the same happens. It does only appear to be on the native apps. Last night although I wasn't getting the constant glitches until I pull the power cable out to resolve but instead the sound would cut off for around 5 seconds and then start back up again.Did anyone, get a resolution to this yet?
Something similar has just started to happen to our TV, same model, purchased in November last year, everything been fine until yesterday however when trying to use the Native APPs we get alot of clipping/blipping on the audio.
Only resolution is to pull the power out of the wall and plug it back in.
Happens with both the AVR output and the local speakers, though not as pronouced on the local speakers. We will trail more setups tonight to see if we can find a common pattern.
Thank you! Previously, CEC was extremely flaky with my JZ980 and Marantz pre-amp. Often the TV would boot with the sound mode setting on 'TV' rather than 'Home Theater', not seeing the pre-amp at all.When it happens, if you go into sound settings does it still show as home cinema, or has it reverted to TV speakers (even though it still plays through external ones). If so, might have a rogue device causing handshake issues (again this is if you have things plugged into the hdmi ports). Suggest unplugging them one at a time and seeing if it fixes it. If it does it will be cec on that device causing all the problems. You can buy a cecless adapter from Amazon to solve it.
Obviously this might be a completely different issue, but this was my problem and drove me mad.
