Just upgraded my main computer from Vista 64bit to Windows 7 Home Premium SP1 64bit. Everything works great but it looks like my USB Dac (Audinst HUD-MX1) ist not willing to work in the new setup.
According to the Windows device manager everything is fine. W7 automatically installs generic USB audio drivers and the MX-1 shows the yellow LED (ready for receiving a signal). Onboard Sound is deactivated in the BIOS and the MX1 is choosen as output device. Still the DAC gets no signal. In my research I found several discussions of similar issues. It seems like Microsoft introduced new USB audio drivers together with the SP1 version of Windows 7 and this might cause incompatibility issues with some DACs.
Has anyone experienced this problem or has an idea about how to solve this?
Thanks a lot in advance!
