I added upstream bug and edited the bug title to reflect that it isn't
related to that specific microphone but a bug in Audacity (or
PortAudio...).

>A playback or recording freeze, recording dropouts or fast playback may
occur when using PulseAudio. Freezes may be caused by repeatedly
starting and stopping playback or recording in quick succession (or by
holding down the Play or Record button). Workarounds: Try launching
Audacity from the terminal with the pulse latency set to 30 ms in an
environment variable:

env PULSE_LATENCY_MSEC=30 audacity
If you get underruns noted in the terminal, try a higher number in the PULSE_LATENCY_MSEC command. If the problem is unchanged, try a lower number. Alternatively, bypass pulseaudio by setting the playback and recording device to an ALSA (hw) choice in Device Toolbar

Title:
  Audacity plays too fast and crashes

Status in Audacity:
  Unknown
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.
