B850M Pro-A WiFi: Analog Audio Output far too low / Manjaro-Linux

Although since Kernel 2.6.9 Linux does support Rembrandt Radeon High Definition Audio and although I checked, that all audio drivers are installed, audio output is very low on front and on back audio jacks.

In contrast, the output level is normal, when audio output is going via bluetooth.

There is a central sound mixer (pulse audio) which shows signal levels for each input and output. The levels seem to be normal and by far not too low.
That let me assume, that I may have a short circuit in the audio cables within the computer. But checking this, showed that everything is OK there.

If I check my Linux with detailed commands like:
aplay -lL
arecord -l
pactl list cards
pactl list sinks
pactl list sources

I get an enormous list of all kind of audio devices and audio api, which I never heard of. I am astonished about the sheer mass.

Does anyone has made similar experiences on Linux? And if so, did you find a solution?
