Comment 2 for bug 232341

All righty.
Step by step starting without LASH.
(Without Jack started)
Start up seq24-0.8.7 that was installed with distro.
Start up ZynAddSubFX (also installed with distro - dunno what version, guessing the latest)
Open song editor in seq24 and add a track.
Select ZynAddSubFX midi bus.
Press piano key (in track editor) to test sound - hear sound.
Add events to track editor and hit play, also set loop to 1 measure.
Plays events and loops just fine.

After installing lashd 0.5.4-0ubuntu2 and lash-bin 0.5.4-0ubuntu2
Start seq24
Start Zyn
open song editor in seq24 and add track
Select Zyn midi bus.
Press piano key in track editor to test sound again - hear sound.
Add events to track editor and set to loop one measure.
Errr... k plays everything fine now. But i did just set memlock and got rt to work which wasn't working when this occurred.
Gonna try to reproduce without the rt/memlock settings added.

Ok, I can't reproduce the bug anymore.
