M-Audio M-Track QUAD compatibility with Pro Tools 11

Hi there all,



Can anyone tell me if there are compatibility issues with the M-Audio M-Track QUAD and Pro Tools 11?



I finally upgraded from Pro Tools 8 to Pro Tools 11 last week, and at same time I purchased the M-Audio M-Track QUAD, but I cannot get them working together at all.



Pro Tools finds it, and I have it selected as Default Card, but although I see the graphics moving up and down in the mixer, there is no sound coming out.



My system is a Intel i7-4770K 64bit system running Windows 8.1 with 16gb ram



Please help, Only have a short time to get it working else it will have to be returned, as it's no good to me if its not compatible.



Kind regards

Rob
