0007503: Sound choppy on linux
New PA code sent to Ian (April 13th). When available please test both play and record *without* monitoring audio levels. PA's audio monitoring utility sets a low latency which will mask any latency problems with Squeak's PA plug-in.

From dmoc:

 It was that post which prompted me to check sound today using 4.0.3.2200.

If you try "Beeper beep" it may appear to play ok because it is a short sample.

If you do it several times in quick succession then it doesn't sound too healthy.

Using the PianoKeyboard morph to play a steady note reveals playback to be choppy. I replaced the PA plugin with a version done for Scratch in Feb and now playback and record work properly.

I've reproduced the relevant portion of dmoc's note so the issue has a recipe for the problem. --Jer
