you need virtualbox verbose log which provide debug messages printed by

the linux driver check those ad specific registers for multi codecs ,

this is dell dimension 8400 with ad1980 which virtualbox 5.0 try to
emulate
the difference of alsa-info between your and the real dell dimension

I don't understand this response.
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
static void snd_intel8x0_codec_write(struct snd_ac97 *ac97,
unsigned short reg,
unsigned short val)
{
struct intel8x0 *chip = ac97-private_data;
+ dev_info(chip-card-dev, ac97 write %d - %.2x : %.4x\n, ac97-num,
https://www.virtualbox.org/changeset/55272/vbox/trunk/src/VBox/Devices/Audio/DevIchAc97.cpp
since it hardcode ad1980 on a dell machine, you may need patch in alsa
driver to prevent the swap of the master playback volume/switch and
headphone playback volume/switch

you need to log all i/o ports read/write of those ich controller registers and
ac97 codec registers read/write
since real dell dimension 8400

do you have any windows guest work with emulated ad1980 codec ?

the easy work around is to use emulated hda instead of emulated ac97
specify snd-hda-intel model=intel-mac-v3

to avoid the driver rename master playback volume to master surround,
you need to specify
ac97->spec.ad18xx.lo_as_master = 1;
only for the enumerated ad1980 codec inside virtualbox
