Reinstalling Dell software, specifically the THX Audio Control Panel, on a Studio XPS 8100.

I had to reinstall my operating system and lost all my Dell installed programs.

So I went to My Dell Downloads and downloaded; THX TRUSTUDIO PC (for Vista or Windows 7)

That got me this file; TAMB_DLA1D_2_LB_ABCD_R1_R254803

After installing I got the; THX Audio Control Panel

When the program opens it shows the; THX TruStudio PC control panel with the message; The current selected audio device is not supported by the application. Do you want to select another audio device now?

I'm given three options; follow Windows Default; Digital Audio (S/PDIF)(2-High Definition Audio Device); and Speakers (2-High Definition Audio Device)

All three devices come with the same message; The current selected audio device is not supported by the application. Do you want to select another audio device now?

How do I get this app working?

Windows 7 Ultimate, 64-bit, Service Pack 1
