1. Execute Scratch using current VM and pulse plugin (on Ubuntu 12.04, 64
Executing: /usr/lib/squeak/4.4.7-2357/squeakvm -encoding UTF-8
-vm-display-x11 -xshm -plugins
(There is no pulse plugin in /usr/lib/scratch/plugins in my installation
package, so it must be using the one in /usr/lib/squeak/4.4.7-2357)
2. Click "Sounds" tab, click play icon next to meow. That results in:
10273532  in SoundPlayer class>playLoop
10262240 SoundPlayer class>playLoop
10273228  in SoundPlayer class>startPlayerProcessBufferSize:rate:stereo:
10273320  in BlockContext>newProcess
Aborted (core dumped)
Note that the same package on 32 bit systems does not produce the error
(playback and recording both work).
The issue is also described here:
If someone can take a look and patch this, we'd very much appreciate it!
This is the last major (known) issue we've got with Scratch running on
