I need some help folks. I've noticed when playing back audio via usb from a mac that periodically the usbpre2 seems to drop the signal. My mac never reports a drop, but metering and any analog signal outbound drops for about 1/2 second. I've tried 2 different macs (fresh reboots) and can repeat the issue. It varies how long it takes it to occur the first time (and varies each time afterward) but it's always under 10minutes. My test on Windows XP yielded a clean test so I'm wondering if it's a specific mac version or what.
Anyway, I have a flac file which when set to looping (via audacity is the easiest way I've found) will peg the meters and peaks so it becomes easier to watch for the dropout. Is there anyone who runs OSX and has a usbpre2 that would be willing to test this on their setup for me? I've been in contact with SD's support for the better part of 10 days now and I've run out of machines/configs to test it on.
