Is this a known issue with RPis GPIO and extension cables?
No. The length of the cable has a relation to electrical resistance, and reduces voltage. A stronger PSU can help to avoid such issues.

I built lakka using your sources. Can I post it on the forum?
You can post a link, but don't upload any image.
PS: That means, you can post a link to an image or to sources. Just don't upload any Lakka content on this forum.

Could the issues be connected?
Possible. At first place I think your test file has errors, because I don't have audio with it. Those errors might lead to a re-initialization of the audio sink. If the EDID file is some sort of a map for the audio sink, then it could help to have correct EDID data.

The thread over at Intel mentions something about the EDID. I did try the getedid create script but it does not seem to save the edid correctly.

Line-by-line comparison between RPi and NUC11 shows a difference here:
RPi:

PS: Click the gear icon on the playback bar. Under video settings search for DRM Prime, and switch it on / off. I'm not sure about the existence of this setting on current x86 builds, because I can only test on RPi.

Upgrading from 9.x.x to 10.x.x will break dependencies. Please install LE 10.0.3 from scratch.

I played the test file from post #1 with this result (RPi3B+, LE 10.0.3):
External Content pastebin.comContent embedded from external sources will not be displayed without your consent.Through the activation of external content, you agree that personal data may be transferred to third party platforms. We have provided more information on this in our privacy policy.It has subtitles and no audio. However, it doesn't crash my audio system, so I still have audio after playing the file.
My current theory is a bad audio driver. It just shouldn't crash, whatever it plays.
-
I gave that topic into internal team channel, but no reply. You have to experiment now.
We can provide further help when you have the DAC.
-
Because LE doesn't have apt-get to install rockpi4-dtbo, it's eventually present as an overlay on LE (check the folder).
So maybe you have to activate two overlays to make a HiFiBerry DAC+ work.
-
Interesting! To my knowledge it's possible to redirect pin functions to other pins. So that's probably what they did in the rockpi4-dtbo.
-
hello, I have a Rock pi4C+, I want to connect a HiFIi Berry to it. Is it possible to run it?
No. All RockPi4 models have the same pin assignment, which is not compatible to RPi4: Click!
Use an HDMI audio extractor or a USB DAC.

Intel users can update to 10.0.3. Only issues on AMD hardware.

The change logs are not very detailed. You have to figure it out by trying the latest nightly: Click!

The log says it all. Go RPi -> TV -> AVR instead, or use both HDMI outputs.
PS: If your setup is just RPi -> TV, then incompatible CEC breaks your audio.
