Sometimes when reboot device goes to emergency mode and you can not connect to it remotelly.

I read on internet, may be here, that make this [Firmware Bug].

I downgrade Kernel to "Igor" recommended 5.7.15 and there the [Firmware Bug] missing.

I tested new and newest Kernel via armbian-config but the [Firmware Bug] is present everywhere.

Kernel 5.7.15 seems good without this bug but i have no sounds on Audio out or via HDMI.

journalctl -xb

[Firmware Bug]: Kernel image misaligned at boot, please fix your bootloader!

 

I can verify both with latest 5.10 kernel. It boots fine but shows this kernel image misaligned error and I fail to setup HDMI audio. There is only one sound card 0 shown by aplay -l which seems to be the 3.5mm jack.

As long as the kernel boots, this message is harmless. The 5.16.0 one I am currently running does not emit it. It's been fixed on mainline for some time, but I don't remember when that was.

Good to know, and yes I cannot observe any issue related to that warning.

 

If anyone has an idea how to get HDMI audio up, that would be awesome. Probably it can be achieved with one of the ALSA mixer controls, though I didn't went through all of them for all sub devices. All sub devices themselves (card 0 device 0, card 0 device 1, card 0 device 2) have been tested.

I can now confirm that HDMI audio is up for me. I am still on my NanoPC-T4 MicroSD card but it was only necessary to insert appropriate Odroid-N2+ configurations.

I used the settings from here.

Got it working with the help of your linked post. I also found some logic behind this, though not yet 100% understood everything. But I can reliable toggle HDMI and 3.5mm output now:
