Preventing Audacity from crashing when using PulseAudio

I found that Audacity would crash whenever the Playback Device in the Devices section of Preferences was set to "pulse" or "default".

This can be fixed by launching Audacity like this:

Exec=env PULSE_LATENCY_MSEC=100 audacity

I fixed it "permanently" by modifying my Audacity launcher file, which is in /usr/share/applications/audacity.desktop.

I changed the line starting "Exec=" to:

Exec=env PULSE_LATENCY_MSEC=100 audacity %F

More info is on the Audacity forum.
