Thanks Richard for that, yes I know in auto play in control panel it is set to use windows media player as default for music in windows 7.

Problem is when I switch on fast track pro the windows media player wont play the files, but once I switch it off then everything is ok.

Its just that a lot of the time I am sort of going between biab and realband where I do have asio drivers, so its a slight inconvenience.

Maybe better for me just to switch to MME in realband too, and just use asio for recording vocals or realtime playing.

Thanks
