Same problem here, but setting PULSE_LATENCY_MSEC does not help.  I
tried to set this variable to some values and on high values (100..1000)
it seems that the problem occurs less often, but it still occurs.

A workaround that works for me is bypassing pulseaudio:
- add the user to the 'audio' group (if it is not already there) and
  relogin
- in audacity, use the ALSA device for playback
