Hello, I take the liberty of asking you because I have a fairly well-known problem that I can't solve.

I bought a Sonos Arc Ultra and 2 Era 300 and here is my equipment:

-LG OLED 65C1

- Panasonic UB820 Blu-ray Player

-PS5

-Apple TV 4K

On my Panasonic UB-820 player, Dolby Atmos and Dolby Digital work perfectly but DTS-HD does not convert to PCM 5.1, it is indicated in PCM Stereo!

My PS5 can convert DTS audio to LPCM 5.1, and it sounds great!

Can anyone help me with this problem? Thank you.

You’ve searched these forums for the Panasonic? As near as I can tell, Sonos doesn’t handle DTS-HD, so you’ll need to change the signal, either in the Panasonic’s settings, or the TV's settings.

Here is a longish thread which might be of some assistance, but there are more:

LG might also not do DTS.
