This damn thing is at again. In the middle of a session, Sonar reports that the Babyface was unplugged, and now it won't playback any audio. I tried everything, updating to the newest driver, roll back to previous driver. I had updated the firmware before and I not sure if there is a way to roll that back but I have exhausted every other possibility. It is not due to faulty wiring or unplugged chords or anything that obvious. Bottom line I have no audio interface right now. Nothing seems to work, at this point Windows cannot even use the device to play back system sounds and no DAW or standalone synth software that I have can use it as an audio capture, playback device. It lists there and install like it is there. I think the unit is faulty, there cannot be any other explanation. This is rather frustrating considering that it was working perfectly for the last few weeks. Was recording some really good sounding guitar tones and then voila, it just stopped working. I rebooted and worked for a couple of more hours and then did it again. Anyone have any other suggestions, I would appreciate it, thanks. As a last resort I am looking into rolling back the firmware, maybe that is a problem for Sonar and Windows I really do not know.
