I'm using version 1.1.3-gcbf6d24 (Linux/x86_64, Qt 4.8.6, GCC 4.8.4) (built from git a few days ago).

Exporting audio produces unusable files - they are sped up, with chopped audio - sounds like a percentage of samples from the audio stream are discarded somehow. Lots of clicks and bad stuff present.

While the rendering is being done, a sped up and messed up version of the track is played back. Sound like JACK freewheeling mode messed up in such a way that the samples computed are played back. But JACK doesn't produce messed up files when this breaks.

Anybody can confirm this issue?
