import hanging indefinitely if pulseaudio daemon is down

[lucastcox]

The issue lies in this code

If I

 import soundcard as sc 

and pulseaudio is not running, it will hang indefinitely while importing because of the the while loop. It might not be a bad idea to specify a maximum timeout and throw an exception if pulseaudio is unavailable.
