I've just bought dr.dac3 yesterday.
Under Win 7 home premium, though my computer can recognize it as a dr.dac3, it can't installed the driver properly. (with exclaimation mark)
According to the manual, it may be related to motherboard chipset driver. I've already update this driver but same problem persists.
When I try to install the driver through the driver download from this website, it initially can play some sound with some noise. Shortly, the system crashed (a blue background with a lot of text).
But when I connected the same dac to my mac book air, it works well without any error message.
Please help! I want my dr.dac3 work well under window 7.
