My new home machine came with a `musical fan' that plugs between
the pc speaker and the motherboard.  If I hold my thumb on the fan,
it plays a tune ;-)  So here's the test: Connect a microphone between
the speaker and the SoundBastard; if pcaudio isn't active and there's
data coming into the SoundBastard, the fan ain't working, so halt. ;-)
