This is my first post on here so I hope it goes well.
Basically I recently updated my computer to Mavericks OS X 10.9 and have found my M- Audio Fast Track Pro doesn't work as a playback engine. It still works as an input, and the mix will continue to play but no sound comes through. I have never bothered figuring out how to update my pro tools or m- audio interface (I know, I was meaning to get around to it, but it seemed so complicated) Will and update fix this problem? I don't know what else could have changed in my settings. I've been screwing aroun with all the options for ages.
Thanks
