Comment:

 Etoys only overrides the Squeak VM's audio auto detection if Pulse is
 running. Before 4.1.2390 it used OSS if Pulse is detected because quality
 was worse in Pulse, now it uses Pulse directly, to avoid freezing:
 http://dev.laptop.org/git/projects/etoys/diff/etoys.in?id=cc6ff35a6ffb39b07cef6726214a0c1b9b16566b

 Unless told specifically which audio module to use, the Squeak VM chooses
 between ALSA and OSS on its own. IIRC it prefers ALSA over OSS. Pulse's
 ALSA emulation is incomplete, that's the reason why dmoco even wrote the
 pulse module.

 You can force another audio driver by passing the -vm-sound option to
 Squeak.
