Hey, been reading this forum for ages but haven't joined because I'm yet to produce anything but I thought I would join now just so I can help someone.
I had the same problem with asio. Fire up the services manager (just services somewhere in the start menu if you are running win 7), find Windows Audio and stop that service, then fire up Ableton. Hopefully it will work then. If not, start the service again as you'll need it for other things.
EDIT: I'm using realtek hd stuff as well... May be the cause of the problem.
