I have just recently bought a new PC which has a AMD Phenom tm 9750 quad core processor with 4.00 GB ram and 64 bit operating system. I am having trouble linking my Edirol UA25 audio interface to the computer. When I go into the sound preferences the only option is sound out though the speakers and no sound in. The midi does not work as well. I have tried down loading drivers from Rolands web site but this does on work. Can anyone help please.
