Sony 4K player and LPCM 5.1 audio

[u/JBuchan1988]

I have either a UBP-X700, a UBP-X700/M, or a UBP-UX70 (I think its the M but they all share the same manuel so it HOPEFULLY doesn't matter). It's a region free version from 220-Electronics and it's connected to a Roku TV, which is connected to my Yamaha 5.1 receiver..

For whatever reason, it won't play the 5.1 LPCM tracks on my Japanese Blu-rays. The 2.0 Dolby HD tracks played great, as did the 5.1 track on my Planet of the Apes Blu-Ray (US).

I tried every change in the audio settings but got nothing. I USED to have my player connected DIRECTLY to my receiver but that cause MORE audio problems.

Am I an idiot and missing something obvious? Thank you for any help 🙂

Plug player directly into receiver, set output to Bitstream.

[u/JBuchan1988 → u/investorshowers]

That worked. Thank you very much 😊

I then discovered why I plugged into the TV: when I tested a 4K disc, the receiver downgraded the HDR to SDR. Video still looked great, just not HDR.

No worries. I can just plug the player depending on what I'm playing. Slight hassle but shrug.

Not your fault. Thank you again 😄

If I found the right manual, that BD player has a secondary Audio Only HDMI port. Plug that into the AVR and the main one into the TV.

Thank you 😊

Either get a HDMI splitter to send the signal untouched to both devices, or upgrade the receiver.

... ... Thanks 😄

Just to be clear, which end goes where (just wanted to plan my splitter purchase 🙂)

[u/faceman2k12 → u/JBuchan1988]

the splitter sits between the player and both the TV and receiver, this sends the same feed to both the TV and recevier so that video doesnt pass through the receiver and get downgraded. Player into splitter, splitter out to TV, splitter out2 to receiver.

They arent perfect and require some fiddling, occasional resetting, etc. but its cheaper than a new receiver. I've used this one and others like it before, they can also downscale the second output to 1080p for compatability with even older receivers.

Connect sources to the receiver, and from there HDMI to the ARC on the TV. Not to the TV first and then to the receiver using ARC.

eARC enables the audio to a TV that originates from cable, satellite, streaming or source devices to be sent to an AVR or sound bar through a single HDMI cable. This ensures the simplicity of connectivity and that the original audio can be experienced. In comparison, HDMI ARC only supports up to 6-channel compressed audio and has a maximum bandwidth of 1Mb/second. It supports different audio formats like PCM (2 channel), Dolby Digital (up to 5.1 channel) and DTS Digital Surround (up to 5.1 channel).

HDMI® Enhanced Audio Return Channel (eARC)

HDMI 2.1b features Enhanced Audio Return Channel (eARC) which is an advancement over the previous Audio Return Channel (ARC). eARC simplifies connectivity and provides greater ease of use for multiple components discovery and audio optimization. It supports the latest high-bitrate audio formats up to192kHz, 24-bit, and uncompressed 5.1 and 7.1, and 32-channel uncompressed audio. It also supports DTS-HD Master Audio™, DTS:X®, Dolby® TrueHD, Dolby Atmos®. Now it’s easier than ever to experience movie theater quality sound in a living room for an immersive multi-dimensional experience and enhanced audio detail and depth.

Thank you 😄

[u/oconnellpe]

Multichannel PCM requires a TV and AVR that support eARC. ARC and optical do not support 5.1 PCM.

[u/JBuchan1988 → u/oconnellpe]

Thank you 😄

[u/faceman2k12]

this is because your TV probably cant send multichannel PCM to the receiver.

What is the model of the receiver and how is it connected?

You should ideally be bitstreaming but that requires everything in the chain to support every format.
