Description of problem: There is no sound on raspberry pi. in pavucontrol the vu-meter is showing sound playing, but no sound in hdmi nor jack output. so it seems a regression of the kernel 4.19 accordingly to this: https://groups.google.com/forum/#!topic/linux.debian.bugs.dist/jNMU5tWf7F0

Hi, Kernel 5.0.0 - no sounds ever, but multiple errors when trying to play souns in logs: bcm2835_audio bcm2835_audio: vhci message timeout, msg=3
hi, desinstalling pulsaudio and setting sound volume with alsamixer make sound working
no necessity to de-install pulseaudio; just use alternatives --config soundprofile to select alsa make sound working So pulseaudio is the problem
Where can I downbload a raspberry pi mageia image?. Regards

I remember seeing some discussion and link on our forum and user dicuss mailing list. Search there.

I can retest in 5.10.25 if needed. Is there a problem with Device Tree? I'm lost there. Don't even know how to check. Besides that there are some *.dtb in /boot and many *.dtbo in /boot/overlays.

pacmd is for pulse audio, but even with alsa tools, on my rpi4 B, [ 0.673389] raspberrypi-firmware soc:firmware: Attached to firmware from 2021-01-08T14:31:16 [ 0.687494] ALSA device list: [ 0.689366] No soundcards found

I think we should create a new bug as Daniels solution doesn't help on RPi4. I tested if files from Raspbian 64-bit *.dtb, *.dat, *.elf, bootcode.bin and overlays content would help with audio. It probably didn't. I tried to boot but the boot was seriously compromised. Wireless keyboard on USB2 was not working, SSD on USB3 was not mounted (systemd reported Dependancy failed). Didn't dig deeper, just quickly reverted over luckily working ssh and rebooted. Any idea how to proceed?
