Vista x64 AC97 Sound Options (mixing wav and microphone possible?) or other ideas?

I've installed Vista x64 on the asus P5n32sli se deluxe motherboard..
When I goto record audio in Nero SoundTrax.. I only have one option
for the device to record.. it gives me "master" as the only option..

There is no option for "mix" or "what you hear" or anything like
this...

I need to be able to record from the microphone port and capture
playing audio on the PC at the same time.

I guess the alternative is to have to buy an outboard mixer device,
but I know this ability existed in XP..

Anyone know of a workaround?

I've installed the latest vista 6213 APO driver from realtek, this
didnt seem to allow more options either.


Thanks
