Sorry, should've asked the followup questions:
Have you tried recording after picking the UA-1D as the Waveform Record device? yes
Did it work? Were you able to record successfully?
Have you tried playing back with *all* the other devices in the Waveform Playback? yes
And with any of these other devices, are you able to playback a pre-recorded wav through CE2000? What about playing back *while* recording? (I think this is the problem you're describing, but understanding the answers to the others may help.)
Were you able to playback via CE2000 (or other applications) before installing the UA-1D? analog form, but not digital through the 7pin
I'm confused...analog form? If the WAV is on your PC, it's not analog.
