Hi folks,

I got it built and running, and now I have run into this problem:

Does anyone know how to get around this?

ALSA generally doesn't share devices.  Something else on your system ( your browser, perhaps) has your sound device open.

If you can, try installing pulseaudio. Then use the device name "pulse" for the audio device. Pulse sits on top of ALSA (generally) and helps with distribution of the audio resources.
