I have a VS-700 and use ASIO.
 
After installing a Quick Time from Apple, I have no sound.  In other words, I can't even play a wav or MP3 in media player.
 
Although I am not sure, it seems Quick Time somehow caused my PC to default to an internal sound card instead of to my audio interface (VS-700).  I don't even see my normal interface listed in Sounds in the Control Panel.
 
Recommendations?

For whatever reason, the second time I rebooted everything (PC, interface, and console), the audio came back.  Odd...

Thank goodness for that!
