I followed your link and tried your build, nice menu but same error: jedec_spi_nor flash@0: unrecognized JEDEC id bytes: 00, 00, 00 Failed to initialize SPI flash at 0:0 (error -2) This error is from U-Boot and Linux gives the same, my first post shows the error in Linux with debugging turned on and a reduced frequency (and vcc-supply) set in device tree. Only Hardkernel's firmware works here.

Hey! i had similar issues with the ES8388 analog and HDMI output path alignment on my OPi5 Plus under recent edge/mainline kernels. Sometimes the card states look fine in ALSA/pavucontrol but the streams just don't bridge to the hardware mapping properly, or the default audio levels are hitting gain issues. To test if it’s just a software-side compression or file amplification issue before diving too deep into modifying the device tree (.dts), try running a quick format check with a known sample using explicit routing- aplay -D plughw:1,0 your_audio.wav If your test files are inherently too quiet or failing to hit the threshold cleanly, you can boost them up beforehand via tools like MP3Louder just to make sure you aren't fighting low baseline source levels on top of the kernel driver bugs. If it completely stays dead silent even with clean, forced audio files, then it's definitely the device tree overlay parameters (simple-audio-card) not toggling correctly on your specific build version. Which image build date and kernel version are you currently on?

The post is from nov 2022, and OP reported it worked 2 weeks later... But good advice non the less... xD

I'd start by checking whether the issue showed up right after an apt upgrade or after updating OMV itself. I've had cases where reinstalling the OMV packages and checking the service logs made it much easier to pinpoint what actually broke. Posting the output of the relevant logs would also help others narrow it down instead of guessing.

As long as you do not provide proper serial console logs, no one can tell what is going on. I can't help you in this situation any further, and you have to find a solution for yourself.
