output selector question

[Michael Gruner]

Hi Tom

Set 'async=false' in your alsasinks. This is a prerolling problem, your 
pipeline wont be able to complete the state change to paused until all 
the sinks receive a buffer, which is an unlikely situation when using an 
output selector. Async=false overrides this behavior.
