Rock PI S audio volume settings

Is there any chance on Rock Pi S to adjust volume?

Im using amixer sset, but if I set 0% it is playing normal and on 100% it is playing little bit more…

I too, am unable to adjust the volume via alsamixer.
Note that all settings are on 0, yet sound still has volume.

I followed the instructions here: Audio Support Rock Pi S
Any help how to control the volume via the command-line/alsa is most appreciated!
