I don't see SoundMAX in here, although surprisingly, when I ran a registry
cleaner just to check on things, there is an invalid reference to the Start
Menu folder SoundMAX, so maybe that was uninstalled long ago (before I got
this).
Instead, under Device Manager, I have these relevant entries:
Device Manager
Sound, video and game controllers
Audio Codecs
IDT High Definition Audio CODEC (see note below)
Legacy Audio Drivers
Under the IDT codec line above, I find:

HDAAUDIO\FUNC_01&VEN_111D&DEV_76B2&SUBSYS_1028024F &REV(etc)
Strange, isn't it. Maybe I should go look up some stuff on SoundMAX.
Up to three devices can be on the HDAudio bus.
A typical usage is one bus decode is for an Audio
Codec, and a second bus decode is for a Modem and
RJ11 to a phone line. That's a config that may
appear on a laptop, not a desktop.
Since your thingy is "FUNC_01", you might expect any
other devices on the bus to have a different decode
like FUNC_02. The company_name of the FUNC_02
device, is unlikely to be anything we've discussed
already.
It would be pretty difficult to bodge in a SoundMAX
driver into the thing, I would guess. It requires
INF editing. Check the INF folder in Windows
for evidence of "wizardry". Maybe it's already
been deleted, whatever they were doing. The only
case of this I've heard of, is people jamming
RealTek HDAudio drivers into other brands of
sound chips - which works for stereo LineOut only.
HDAudio may have sufficient "standard" register
definitions, that all devices can be run with
a single "stereo" driver. I've never tried anything
like that.
Now, the question would be, can one audio driver
foul up a second hardware instance. And my home
experience here is (unfortunately) yes. I had one
sound card, damage a global setting used by all
sound devices on the computer. I caught the
little ******* with ProcMon, but it took quite
a while scrolling through 100,000 registry calls
until I found an actual (wrong) "entry not found".
There are all sorts of "entry not found" entries
in a ProcMon run. My job in that case, was to
recognize one that was crucial to any sound card
to be working.

See ? People do idle away the hours hacking drivers.
Imagine the mess this will make.

I've played the Dell game before. They have drivers that
other makers don't offer, newer drivers. The trick
is Googling to find the actual latest one, which
isn't easy.
The reason I had to play the Dell game, is my SoundMAX
on my old P4 system, used to "pop" every ten minutes,
which would blow you out of your seat. Quite unpleasant.
Various Asus drivers, would change the time between
pops, from around 10 minutes to 20 minutes.
I think I eventually found an even later driver on
the Dell site, that fixed it. Thank you, Analog Devices,
and your crappy driver policy...
Good luck with your (what might be) Sigmatel.
