I'm using Real Band to record a clarinet track over an MP3.

When I'm recording my performance, everything sounds fine, but when I play it back, my clarinet track lags by what seems like 20 milliseconds.

I'm using a Windows 10 computer with an external Creative Sound Blaster X-Fi Go! Pro USB "card" that uses an MME driver. (ASIO not supported.)

I've tried different recording resolutions, but that doesn't seem to help.

Can anyone think of any other approach to fixing this latency problem, other than switching to a more sophisticated card that uses ASIO?

Your suggestions are welcome.
