Steve, can I get you to try this again as portaudio has been upgraded.
I have not gotten it to freeze, but I do get strange results with pulse.

I have 32-tracks of Chirp and if I have the "pulse" device selected, the
first time I Play it sound just fine.  But I get a lot of skipping of
the playback and tons of these messages on the console:

ALSA lib pcm.c:8526:(snd_pcm_recover) underrun occurred

Title:
  Audacity plays too fast and crashes

Status in Audacity:
  Confirmed
Status in audacity package in Ubuntu:
  New

Bug description:
  I use a Samson «Go mic» for recording audio with Audacity. I connect
  my earphones to the mic and use it for hearing both my own voice live
  and the computer sound (I have to select it in Ubuntu's sound output
  settings).

  This works fine for a while, and I can record and play back through
  the mic. Seemingly randomly, however, pressing play or otherwise
  trying to start playback sometimes makes Audacity skim quickly through
  the audio, playing garbled sounds which I assume are a fast forward
  version of my audio. Sometimes, it resumes normal playback before it
  reaches the end of the file, and everything seems fine. Most often,
  though, it does not, and pressing the stop button or anything else
  crashes Audacity. If I restart Audacity and restore the autosaved
  audio, the problem persists. However, selecting another audio output
  in Ubuntu's sound settings fixes the problem.

  I recently upgraded to Ubuntu 15.10, but this has been a problem since
  at least 15.04. I now use Audacity 2.0.6-2build1.
