Snow Leopard and mbox 2 mini
 

I switched from Leopard to Snow Leopard and now i have problems of clicking in playback. I have a 2008 Intel macbook 4 gb Ram, Pro Tool 8.0.5 and mbox 2 mini. I can't find details on the best driver version for my set up. Now i've installed driver 105, before triyng installing 107 i want to be sure, in any case can be a driver problem?
