What results do you get if you boot your system with the USB speakers disconnected and the connect them once the system is fully booted?
I was listening to some audio when the sound stopped; AudioEngine had disappeared from the list of output devices. A log extract is attached (Audio-Crash.txt).
There may be a problem with the cable. The speakers are attached to the computer with a USB extender cable, which may not give as good a connection as is needed. So I moved things around and connected the speakers without the extender; we'll see if things get better. A log extract is attached (Audio-Restore-ShortCable.txt).
