Summary

0007503: Sound choppy on linux

Description

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.

Notes

(0013710 - 556 - 631 - 631 - 631 - 631 - 631) wiz 04-14-10 01:48	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
