As John mentioned; if MME works fine, use that as a basis, and then deal with the ASIO issue when you *need* ASIO features.
Also note - sometimes the most recent ASIO driver is not the most stable on a given system. Personal experience and other posts have verified this. Maybe the driver two versions ago will work better in your environment. That's why most companies list multiple drivers for download insted of just the latest/greatest.

Like I've said before; ASIO can be finicky for some. Usually you can get it work with a little effort, but if you don't need it why spend the time on it? When you need it, it is nice to have, but many use it for no reason.
Your problem sounds ASIO driver related so far.
How much time you want to put into setting up ASIO on your system is your call.

I do not work here, but the benefits are still awesome
