[chuck-users] Problem with multiple audion sources

[fernando alonso]

I recommend you that install the new chuck 1.3.3.0 beta 3 version. It
included support to pulseaudio.

ChucK source (version 1.3.3.0-beta-3):
http://chuck.stanford.edu/release/files/beta/chuck-1.3.3.0-beta-3.tgz

Chuck branch (of trunk)
