I am not an experienced programmer with respect to these platforms and have
no control what Virtual Box presents back to the OS.
I will say that this problem effects multiple distributions.
You should study the ad1980 datasheet
take a look at the functional block diagram
there is an ac97 mixer which mix the Front DAC signal ( controlled by PCM Out Volume) and other analog input sources (CD , Mic , Line In, stereo mix playback volume)
