[Debian-med-packaging] Bug#790120: praat: sound playback delay, random freeze after about 10-20 playbacks

[Rafael Laboissiere]

Control: fixed -1 6.0.4-2

Thanks for the feedback Jonathan.  I am hereby closing this bug report. 
According to the upstream changelog [1]:

  6.0.05 (8 November 2015)
  * A manual page that describes TextGrid file formats.
  * Corrected a bug that prevented some KlattGrid tiers from being edited.
  * 32-bit Linux: correct use of PulseAudio (note: 6.0.04 on Debian already had this correct).

Best,

Rafael Laboissière
