This is a known bug, but we haven't figured out how to fix it yet.
You can try plugging your headphone in. (one user got his OpenUtau to work in this way)

Sup! Faced the same problem. I connected the headphones to the computer and it started working.
Before this, no audio output was connected to the computer. Perhaps the problem is with the audio output device driver?
