Windows XP SP3 x86 host
Windows 7 Beta 1 x64 guest
I have a "Multimedia Audio Device" in device manager with a yellow exclamation point. Windows Update finds no further updates; I instructed Windows to automatically download drivers from the web, but it didn't make a difference.
I pointed the Update Driver wizard to an extracted Guest Additions drivers folder, but it found no drivers for sound. I tried the SB 16 driver, but then the "Multimedia Audio Device" disappeared altogether. I tried changing "Windows 7 (64-bit)" under OS Type to "Windows Vista (64-bit)", with no change.
All I can assume now is there is a conflict because I'm running XP x86 (Athlon X2 64 processor) for the host. I realize this isn't the ideal setup, but I don't have a copy of XP x64... Any other ideas before I delete my VDI?
