LG C9 + Arc + UB820 / Multichannel PCM for DTS Blu-Ray discs

I’m running an LG C9 with a Panasonic UB820 Blu-ray player, Sonos Arc + Sub gen 3 + One SL surrounds. The lack of DTS support on the Arc has been frustrating for non Dolby encoded Blu-ray discs, so I have been eagerly awaiting the multichannel PCM update.

It’s finally arrived (thanks, Sonos!) and I tried playing a DTS encoded Blu-ray and… no dice. Still stereo PCM 2.0. Has anyone running a similar set-up managed to get 5.1 PCM output from the Arc?

The C9 supports eARC and multichannel PCM, I’m using 48gbps HDMI cables that support up to 8k60Hz, all of the devices are up to date, I have the C9 set to PCM with eArc enabled, DTS output set to PCM on the UB820… I’m really at a loss here. Any ideas or suggested settings?

    There is the HD Fury Arcana, the Feintech VAX04101k, and the OREI HDA-935. You can also order from those links from the companies directly, or check your local retailers for availability. Amazon may carry some, depending on location. At this point, there may be more manufacturers, I haven’t been keeping track.

    I have a c9, ub820, Sonos system(arc, sub and rears) and Nvidia shield. With the shield playing bluray remuxes with DTS-HD MA I get PCM 5.1 but with the ub820 i only get PCM 2.0

    I have tried the settings in this thread but no luck. Any ideas?

    I can turn off e-arc on my C9 and get DTS surround 5.1 but would prefer to have PCM 5.1

    Is your C9 and UB820 up to date with the latest firmware update?

    Yes, 05.40.61 on the C9. UB820 does not say version but no available update.
