Actually, I find it better to keep the built-in PC soundcard activated. I then assign that to Windows and use my audio interface exclusively for audio software. That way, Windows doesn't try to interfere with the audio interface. Plus, I can still use Windows Media Player and other Windows software that requires audio output.

I agree with Scott and I took it one step further, using Pedalboard which is a VST host and Virtual Cable which is exactly what it's name is, I run my built-in card through ARC so everything off web pages, cd's, mp3's, etc. are corrected through ARC.
