ARC outputting Stereo PCM when playing 4K Blu Ray

Hi all,

I recently upgraded my Beam Gen 2 to an Arc and ever since I’m only getting Stereo PCM outputted when I play a 4K Blu Ray that outputs DTS HD. This was working fine on my Beam 2 and it would convert this to PCM Multichannel 7.1.

My set up:

TV - LG C1 - Passthrough and eArc enabled

Sound - Arc, Sub Gen 3, Era 100’s x2

4K Player - Panasonic DP-UB450EB-K

Dolby Atmos works fine but since changing to an Arc it’s only converting DTS HD to stereo PCM.

I’ve looked through all the posts on here and it seems a lot of people have had this problem before. I’ve amended my settings on the Blu Ray player but this hasn’t worked.

Any help would be greatly appreciated.

Thank you

Thanks for your continued help.

Yes just done that and same result unfortunately. I’ve also just replaced the HDMI cables which are 2.1 high speed but this had no effect.

I’ve also just done a hard factory reset of the 4K player and this also made no difference. So frustrating.

Did some more testing and played the 4k disc in my PS5 which outputted PCM multichannel 7.1 without issue. The only issue with the PS5 is that it doesn’t support Dolby Vision.

To correct my original post my 4K Player is a Panasonic DP-UB820EB-K.

So if this outputs the correct audio on my PS5 does the issue lie with my 4K Player?

I’ve copied all the settings suggested on the TV and 4K player. I’ve also hard reset the 4K player and changed the cables but still get stereo PCM.

I have the same model Blu-ray player connected to an LG C3 and have no issues with getting Multichannel PCM audio.

Is the firmware up to date on the TV?

If you go through the audio options using the Audio button on the Panasonic remote while the movie is playing, does it make any difference?

Yes no update available for the TV as it has the latest and I recently did update the firmware on my 4K Player too.

I’m pretty sure I tried that and didn’t seem to make any difference. I don’t want to get rid of my player as it’s one of the best around but just can’t understand why it’s suddenly started after swapping my Beam 2 to an Arc.

Sounds like a few of us are having this. Have you got the LG C1? As wondering if this is to do with the latest update.

Yes I do. Also tested it with my ps5 and was outputting dts-hd movies with the correct pcm 5.1/7.1. Not sure how some people got theirs to work. Tried just about everything

Yeah exactly the same as me. All fine with my PS5 but no longer working with my Panasonic 4K player. No idea how we get this resolved.
