Bug description:
Binary package hint: squeak-vm

When running Scratch with this VM (1:3.11.3+svn2147-1ubuntu1 ) on Lucid, sound playback using the vm-sound-pulse plugin is choppy, as is sound recording. 
To test:
1. Install squeak-vm and Scratch (http://info.scratch.mit.edu/Scratch_1.4_Download )
2. Run Scratch using this VM, rather than the one that is currently bundled with it:
squeak -vm-sound-pulse /usr/lib/scratch/Scratch.image
3. Select Scratch Cat sprite. Click "sounds" tab, play button on "meow."

The current version of Scratch bundles its own VM and pulse plugin that works well (just run scratch without specifying this vm to test).  The source code for the vm-sound-pulse plugin that Scratch uses is available here, as is the binary:
