Comment(by danielk):

 (In [20310]) Refs #5473. Adds a check for PulseAudio at startup of
 mythfrontend and mythtv. PulseAudio causes delays that range randomly
 between 500-2000 ms when playing back audio, so we abort startup if the
 pulse audio server is currently running.
 Note: I've referenced a ticket that adds PulseAudio support to MythTV, but
 even using the PulseAudio API's the delay is still 300 ms; if we can get
 that down in the 20 to 50 ms range we can adjust when we display the video
 frames to compensate for the delay (which we should be doing anyway when
 using multiframe deinterlacers).
