   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?

	I have worked on an issue with malfunctioning DisplayPort, which is discussed in this thread: https://forum.asrock.com/forum_posts.asp?TID=109467&PN=2&title=asrock-b650m-hdv-m2-boot-to-bios After I had switched to HDMI display out, I could get audio signal level of the same level, as on other computers. Of course this is due to the fact, that my display has an integrated DA-converter and it processes the digital data, which are delivered from the mainboard. I suppose, that the DA-converter on the board or the following amplifier are somehow programmed to a low amplification level. But if this would be true, many more people her would discuss this here. On the other hand: Software delivers digital audio data to the hardware and the hardware should transform this data in an adequate analog audio output. Therefor I do not see, that the audio issue has to do with my OS, which is a Manjaro-Linux. In the BIOS I have activated the HD-audio feature. I don't know, whether this would influence my issue here.
