I would hesitate to say RB doesn't like MME, I and many others use it regularly without issue.
It is likely a setting somewhere in your system on how Windows and RB cooperate while using your selected MME driver.

Which actual MME Driver is it?
I have usually found it beneficial to NOT use the Windows Sound Mapper driver (or Windows MIDI Mapper driver for that matter either) but rather the driver actually meant for use with the device being used for sound.
Do you have other options available in the Options-Preferences-Audio Tab-Drivers Button area?
Have you tried them as an alternative?
