HDMI0: 4K video on TV - HDMI: audio on Receiver - All looks good in GUI, no sound - Works with FHD TV

Hello,

Due to logistical issues, I come with no logs at all, so this is more a question on principles. I'm bracing for "no logs, no problem!"

Running L10 nightly (20210424) on RPi4 4 GB.

HDMI0 connected to TV

HDMI1 connected to Denon AVR-2310 receiver (a 1.4 model that won't deal with 4K HDR or ARC, let alone eARC)

The goal of dual heading is the classic avoidance of a receiver upgrade...

Case with 4K HDR TV - Sony XH90

TV and receiver turned on and set to proper inputs before powering the RPi to avoid EDID issues.

Drool-worthy 4K HDR video. Wooooo!

All the audio settings, Normal and passthrough, show the availability of the Sony TV and Denon receiver. I chose the Denon receiver.

I get no sound. No GUI sound, no passthrough.

I've reset my receiver's processor and completely, no positive result.

Case with old 1080p TV - Some Toshiba from 2007

Only the TV is different from the above.

The receiver produces all the sound, GUI and passthrough.

Riiiiiiight.... I know, no logs... I promise to generate them properly, full pastekodi and all, full EDID info, etc. if/when I can logistically put the 4K TV back in play. I fully that this is the only way to make real progress.

But!

Is there any known issue that I should be aware of?

When/if I can get the 4K TV back, is there anything in particular that I should be careful with? Any trick? Any specific data that I could collect outside of a pastekodi or 2 with debug logs and EDID?

Thanks!

Take a read through following thread may provided pointers, maybe Denon AVR-2310 doesn't know what to do with Audio only HDMI input?

Thread

HDMI Passthrough RPi4 - AVR detection

I've tested a few nightly releases and everywhere I have to have my AVR turned on during LE start. If it is only in stand by mode then LE will not detect it sees my IT connected to the AVR instead. If I reboot owing to whatever reason I will not have high DTS options available. My AVR is not very typical because it is coming from SONY MDR-HW700DS 9.1ch Digital Surround Wireless Headphone.

Currently I have LibreELEC-RPi4.arm-9.80-nightly-20201231-b257060.img.gz on Pi4+ HiFiBerry Digi+. I can…

And I would read through AVR manual carefully as perhaps you need to make HDMI setting adjustments on the AVR?

MikeKL you make a valid point.

Well, up to the moment when the same sort of setup works with a different TV, hence my head scratching...

I had gone through that thread already, but will do again, I may have missed an important bit.

Riiiight...

I've started collecting the pastekodis with debug logs, EDIDs, etc. for single headed and dual headed using the old 1080p TV.

That way a good chunk of work is already done for when I get the 4K HDR TV back in to play.

I'll reopen a thread when ready.
