VISTA users.

You really do not need extra drivers using Vista. I can connect mine two ways. One using the USB device output in the sound device menu or the Digital output device(spdif).

You can select kernel streaming as your output for the playback software you use(if it has this option).

It will probably be easier to use the WMP for playback as it is basically plug and play like Itunes is for MAC.The WMP is much better in Vista than it was in XP.

No not necessarily....well maybe. If you do not already have the Sigmatel High Definition CODEC in your sound device menu. You can go here and download the driver. That's if you have an integrated Intel Desktop Board with Sigmatel in your PC. The CODEC allows you to choose from 8 different sampling rates 16 and 24 bit from 44.1kHz , 48 kHz, 96 kHz up to 192 kHz.

Does your PC have a coax or optical output built in?

I use a USB Dac.So no need for the extra USB converter. I pick USB Audio Device as my default output device in the sound device menu. I have used in the past the Trends Audio UD-10 USB converter. It doesn't need any special drivers installed either. The PC recognizes it from the start.

The sound device menu is in the right hand corner of your screen. Just right click on the speaker icon and left click on sound devices. This will bring up the menu.

The on board HD sound card codec is good enough, to make it very difficult to hear a major sound quality difference. They do sound different, but the on board is really not all that bad.

When I feel experimental, I run a toslink and USB cable to my Dac from the PC. I can switch from USB to spdif at will.

I'm not familiar with that unit. Does it require a driver? If so you may need to install it. That or get a USB DAC or USB converter which is recognizable.

How about give it a try Eandylee. The USBaudio driver does support more than what's listed on the website. The demo copy is free. There's only one way to find out.
