here's my issue:
i can record a real instrument (guitar plugged into MOBILEPRE USB interface) in mono for an indefinite time. when i record in stereo, the audio drops out after a few seconds. at this point you have to re-boot MOBILEPRE's driver (switch to "internal audio out", then back to MOBILEPRE's driver) for ANY sound to come out again.
i updated the driver to the most recent 1.5.10f1...the same thing happens, (audio drops out in stereo record mode).
something is not kosher with this driver. any info would help.
a very nice mac!
