Pro Tools LE 8 Mbox 2 mini in Windows XP VM -- distorted audio.

[datacrime]

Hey there,

I'm trying to archive my old XP studio machine so I can get rid of the computer and bulky hardware but still access the sessions if need be.
I imaged the drive and am running Windows XP as a virtualbox VM on my new system.
I replaced my Digi003 with an old Mbox 2 mini as it's smaller/easier to keep around and would still let me access my old sessions.

Everything is set up and working okay, except the audio from the output of the Mbox is very distorted, it's a digital kind of breaking up -- not the signal being too hot.
This happens for any sound played through windows and through the Mbox, which leads me to believe it's not a Pro Tools setting.
Windos audio also plays fine from the VM if I route it through my normal speaker set up instead of the Mbox (although this is not a USB interface, so there's a chance it could be an issue with the USB passthrough on the VM).

I'm imagining it is most likely a driver issue. The Mbox was installed automatically and detected by Windows XP, however I noticed Windows XP installed drivers that appear to be for the newer Mbox series (black model) and I don't know if they have legacy support inbuilt. When opening up the Mbox Mini app from system preferences it said hardware disconnected, so I at least assume legacy support is not fully functioning if there at all.
I uninstalled these drivers and have been on the hunt for Digidesign-period Mbox2 specific drivers, but all the archive.digidesign.com sites I have found linked to seem to be down.

Does anyone have these drivers or does anyone have any other clues on how to troubleshoot this?
