ao segfaults if an AudioDevice object is created too quickly after import

[Mark Edgington]

It appears that pyao requires some setup time after the ao module is imported, otherwise instantiating an AudioDevice object causes a segfault. Test code is below:

--- BEGIN PYTHON FILE ---
#!/usr/bin/env python
import ao

# prevent weirdness with ao segfaulting when AudioDevice is instantiated
#import time ; time.sleep(1)

# PulseAudio sample-specification seems to be sr=44100, num_channels=2, 16-bit
dev = ao.AudioDevice('pulse')
--- END PYTHON FILE ---

I'm using Ubuntu 13.04 (64-bit).
