With multichannel PCM now possible what 4k UHD players have functionality to output DTS soundtrack disc as PCM 7.1?

I will start with Oppo203 that is working perfectly through my C9 then onto ARC.

Any other players doing the same?

Hi

 

What settings do you have set on C9 and Oppo 203 please, I cannot get audio on my 203 since LPCM update, I have the CX that cannot pass DTS but before I got stereo 2.0, now I get nothing.

Normally my Oppos is set to Bitstream for Atmos but changing to LPCM (bottom image) enables the Sonos system to play PCM7.1 (or 5.1 depending on soundtrack on the disc).

LG C9 settings also attached.

 

Hopefully not something LG has done in their CX upgrade to prevent this working for you.

Hi @BW_falkirk 

 

Thanks, same settings here, this is annoying then, I don’t know where the issues lies, but it sounds like it could be the CX, I know DTS passthrough is a no go, but it should pass LPCM.

Did you previously use the SPDIF to play DTS soundtracks as Dokby Digital 5.1? Just in case you weren't aware that's another option. I just added an HDMI extension to the ARC so I wasn't always changing the HDMI cable into the ARC and potentially damaging the port.

Just meant manually changing input (from TV earc or SPDIF from oppo ,(using HDMI convertor) into the extension

No just HDMI, perhaps I should try turning off my devices and back on, I did test it straight after I updated.

Maybe. If its the CX thats the issue then using the Oppo SPDIF output to at least get Dolby 5.1 instead of DTS is the best I can suggest.

    hi @BW_falkirk 

     

    Fixed it, just turned off TV and ARC and now get multichannel 5.1/7.1 from DTS discs, sounds much better now.

    I guess the TV and ARC just needed to re negotiate the new format after the update, I must of tried it a bit too soon after updating.

    Thanks
