The fix is the same as the fix for the sound issues in Skype:

sudo sed -i 's/^Exec=.*/Exec=env PULSE_LATENCY_MSEC=30 audacity %U/' /usr/share/applications/audacity.desktop

Thanks for the fix... It works but not if you launch from the command line or by selecting an icon.
I added:

PULSE_LATENCY_MSEC=30
export PULSE_LATENCY_MSEC

to my .profile
