Thanks for the quick response. Unfortunately that didn't resolve it. When I disconnect the USB cam the sound works fine and the countdown starts. It is only when I have the laptop webcam disabled and the USB camera connected.
I'm actually am a software developer so I will try and narrow down what changed and let you know for future reference. Since our last convo....the only change I made was closing spark booth and reopening it. All settings remained and no new drivers installed.
