It is the operating systems that are causing these problems and confusions, not the device. Dont blame the device or the driver. If you install the driver according to the instructions and select the device in preferences, it just works."
Steve, I've been using computers since '95 (self taught/administrator on UNIX/IRIX SGI, WIN DOS/NT/2K/XP, and MAC OS X). I know how to select the sound output device under OS X System Prefs. Evo showed up after installing the driver, but would only play through iMac speakers. Is that clear now? I've used other USB DAC's and converters and know what I'm doing. Don't just presume user is to blame.
Fyi; There was no mention on the M2Tech website about a driver being needed. And at first I ignored the small folded 2"x5" strip of paper included in the box that informs the customer they'll need to download the instruction manual and driver. But I'll accept the blame for that one. I should have known that tiny scrap of paper held the answers. Point is, set up on OS X is easy, practically does it on it's own (yet look at the WIN instructions. Geesh!).
