I've tried the EDID config

So you've created your own EDID file like this, right?

Sep 20 19:09:07.151062 LibreELEC kernel: ACPI: [Firmware Bug]: BIOS _OSI(Linux) query ignored

Make sure your BIOS is up-to-date.

First: JACK is not our problem, because we don't use it on LE. However...

a) I'm not sure whether RPi is capable to handle more than two JACK channels. Maybe overclocking is needed.

b) To rule out processing issues, try a muli-channel JACK setup on a regular X86 PC first.

c) Patchbox OS has a low-latency kernel, and JACK is pre-installed. Try it, they also have a forum.

If you have more questions about JACK, open a new thread at Off-Topic section.

Likely a kernel issue: Cannon Lake PCH cAVS (ALC892) not detected by kernel driver

Please describe the complete wiring of your A/V setup. You've mentioned a connection to TV and VGA. Are both active at the same time?

The successful ALSA configuration on Ubuntu was probably an audio mapping from one DP to the other. You can't have multiple audio outputs at the same time. Maybe the audio is routed to the VGA, not to the TV.

The specs say that you can only use one DisplayPort:

NOTE: When configurable I/O port has been configured, one DisplayPort might be blocked in select configurations.

Is that true for your setup?

But I am so in experienced, that my pin 5 and 6 probably are 35 and 36

Pin 5 is GPIO 03, pin 6 is Ground (same height, but the other column).

You'll find diagrams on the internet about pin vs. GPIO numbering.

We don't support outdated LE versions, so please update.

Does Bluetooth work now?

Congrats! Stay with RPi OS, and put Kodi on autostart. It's good enough for 7.1 audio.

It looks like it is the end of my Odroid C2 tests as multimedia center.

Not so fast. As mentioned, chewitt also has a C2, so stay tuned until he did some testings.

Not a log.

lich000king Can you try your audio interface on a regular x86 Linux PC, which has Kodi installed? Then you should also have the "JACK sink" output option. I'm asking because I'm unsure whether it's a JACK, or a driver issue.

Quote from HiassofT

Under the hood JACK is using ALSA (as that's the only way to access audio devices in Linux). So adding JACK to the chain is at best a workaround for some kodi bug.

I've described my current theory at post #12. If I'm right, then JACK is not just an optional addition to the chain, but necessary to get any output channels for that specific device.
