Wavefile Source does not stream its audio to the end of the file.

I am attempting to send the output of a Wavefile Source to an Audio Sink as a test for inclusion in a larger project.

 

The flowgraph consists only of the Source block ( 12000 samples/sec), a Rational Re-sampler with interpolation of 4 and the Sink (48000 samples/sec). The wavefile is 15 seconds long and plays properly using SMPlayer.

 

When I run the flowgraph there is only a short burst of audio (measured in ms) and the flowgraph terminates.

 

What is wrong here? I expected the flowgraph to run for 15 secs.
