I‘ve been using Vista RC1 since November. The Off-Ramp I believe comes up as a USB Audio Device, correct?
It should be no problem. I have a Scott Nixon USB DAC that woks fine. I’m using it with iTunes (even though Apple says it doesn’t work – works fine here! Always has) with a MultiPlugin app that allows Foobar2000 to be used as an iTunes playback engine. Sounds wonderful.
My buddy is using Vista Ultimate without any issues and I have it running at work on a Domain network also without any problems. The comment that everyone is having problems is silly. Thousands upon thousands are buying it and dealing with the lack of drivers from third party vendors – maybe that’s what they mean when they say it’s a problem. I don’t know but I’ve been using an old Release Candidate which is supposedly full of bugs and it works very well. I have been video editing (professional) with Abobe Premier Pro, using other Adobe products, done some web editing with Macromedia and I have a long list of apps installed that all work fine. I VPN into my office and Remote Desktop control a slew of XP machines and Servers remotely.
But, yeah. Unless the Off-Ramp uses a third party driver (like from M-Audio or EMU) that is not yet available for Vista it will work fine. MS included a very long list of product drivers and default drivers but most USB audio devices can work easily as a “Standard USB Audio Device” in Win2000, WindowsXP and WindowsVista.
