[pulseaudio-discuss] aplay getting stuck in pulseaudio sometimes

[Jim Duda]

I'm running pulseaudio 0.9.6.  I use aplay to play the output of the 
festival voice sythesis program.  Many times (once or twice a day), I 
find that aplay is running at 100% cpu and appears stuck or spinning.  I 
have to kill the program in order for more audio to be played.  I've 
only seen this since I've been using pulseaudio (which I really like).

Can anyone explain what might be happening?
