Like it or not (personally I am in the second category) Blackboard Collaborate or Elluminate (as it is still more commonly referred to) is something you have a hard time avoiding if you work in online education.
I discovered that I have audio issues on some Ubuntu Linux machines and found the following to fix the issues.
1) Install alsa-aoss
apt-get install alsa-oss
2) Save the Elluminate Java Webstard (.JNLP) file to a local folder – DO NOT OPEN IN BROWSER
3) Launch Elluminate using this command (in the folder you saved the JNLP)
aoss javaws meeting.jnlp
Thanks go to all people involved in this forum thread: http://ubuntuforums.org/showthread.php?t=1081899
1) This assumes you are already running Sun (Oracle) Java JRE not the default OpenJDK as apparently Blackboard Collaborate does not play nice with the default OpenJDK. I have described the install on 11.10 here.
2) Make sure you have updated the alternatives for javaws (install only sets the java alternatives).
update-alternatives --config javaws
