Rock64 v2 - did not work song / audio

[sqw200zu]

HI
I have Rock64 v2. I ran debian 11 on it. It works.

How to turn on the sound on the headphones? On HDMI, sound and picture work.

alsa-utils is installed

speaker-test -c2 -D hw:0,0    --- headphones - it's quiet
speaker-test -c2 -D hw:1,0    --- HDMI is ok

It works on Armbian 22.05.3 Bullseye with Linux 5.15.48-rockchip64, but you can't control the volume. :/

There is no analog output interface (3.5 mm jack) in your list. I have the same problem on Linux rock 6.1.0-18-arm64 #1 SMP Debian 6.1.76-1 (2024-02-01).

If you look in the rk3328 Device Tree file (located in /boot/dtbs/.../rk3328-rock64.dtb) file, you'll find three nodes related to audio:
1. spdif-sound
2. hdmi-sound
3. analog-sound

Check the "dmesg" output. I have this message:

Code:

platform analog-sound: deferred probe pending

Have no idea what's reason for this problem.
