To get better and 5.1 sounds with my home cinema amplifier, i bought a DIGI+PRO soundcard. After many tests and reading topics, it's not posible to use these soundcards with PI4. I seems to be an issue from the driver. We have to wait for ...
Did you set the right config.txt option?
Great! The trick is to go to the forum's main page first, and then press the magnifier icon. Search results will include all sub-forums that way.
Yes, use our search function, and you can find this. 
Other people had the same (good) idea on this forum. The answer is still no. LE / Kodi development is miles away to do such things. Use an HDMI audio extractor instead.
It's probably due to a bug from a long outdated build.
I hope you don't try to sneak in with an OpenELEC question. Stone age is over.
It's a GPU thing, not CPU. The GPU provides hardware acceleration for video playback. On the other hand, the GPU has to work hard (non-accelerated) when displaying EGL graphics, which is used by the GUI. I think your RPi is responding normally.
The MPD add-on is probably just compiled to deliver IP port binding.
CodeNov 09 16:57 : exception: bind to '0.0.0.0:6600' failed (continuing anyway, because binding to '[::]:6600' succeeded): Failed to bind socket: Address already in use
Usually 127.0.0.1 is the right address for local host.
You can also change the firmware on LE, but it's easier on Raspbian. After changing the firmware, you can insert your LE card and instantly use it (firmware is at the chip).
At the 2GB variant, this result was expected. I guess the data bus is too slow for 60Hz plus AAC audio at the moment. Wait for optimization updates.
I never heard about channel mapping on LE. You had a working system before your microSD died, so I think it's not a driver issue.
Because you have another HiFIBerry card, we can rule out a HiFiBerry firmware issue.
On the other hand, the RPi has it's own firmware, too. LE installs the right firmware, but maybe something broke while your microSD died.
My suggestion: Take another microSD, install Raspbian, and if Raspbian also has channel issues, try different RPi firmware on Raspbian.
I understand if this openelec build is a POS, but am I doing something wrong, here?
Yeah, you did something wrong, because this forum is about LE, not OE. So please stop asking for OE things.
This is unusual, and I suggest to provide a link to a complete kodi.log.
To rule out a hardware defect, you can also try a different OS, like Raspbian.
Always use the search function before starting a new thread: Click.
OK, then I don't have a clue how to restore that. The cache folders content is all, what can be deleted without a doubt.
This one:

kaputnik Thanks. Dev's will have a look at this, soon (maybe wrong RPi4B compiler flag).
