Ok...so I ran my M1 to my Delta Dio 2448. I made sure that the sampling rates were all matched correctly and whatnot, but everytime I played back the file I recorded onto the pc, it was sped up. I've heard of this situation occuring before, but only when sampling rates were unmatched.
fwiw...I made sure that the actual card's settings were matched to cdwave's settings.
?
I had the same thing happen to me when I rebuilt my machine recently - turns out I did not, in fact, have the soundcard drivers installed correctly or the card and software configured correctly. As a result, no matter what software I used it always sounded fast.
I'd double check your work one last time before looking for another software solution. If you've already double-checked, I'm no help - I don't have any extra software licenses.
