… played around with the dietpi-config Audio-Options, reboot and use alsamixer

Now i have on hw:0,0 (rockchiphdmi0) an audio signal over my monitor.
speaker-test -c2 works.

Switched back to device hw:4,0 (rockchipes8316), reboot and use alsamixer.
No audio, but i hear a “plop”-tone when i switch some options with alsamixer.
speaker-test -c2 don’t works, only a “plop”-tone was created…

Please try to enable the auto-conversion plugin in dietpi-config audio options.

Hi.

apt install linux-{image,dtb}-vendor-rk35xx.

root@rock5b02:~# uname -a
Linux rock5b02 6.1.43-vendor-rk35xx #1 SMP Wed May 29 01:45:25 UTC 2024 aarch64 GNU/Linux

reboot

Now hw:4.0 works after some playing with alsamixer.
