Elluminate, OpenJDK and PulseAudio

I was constantly having sound issues with Elluminate after my upgrade to Fedora 15. The audio had recurring silent pauses about one second long. It was driving me crazy when I was watching recorded sessions (for on-line ones we are using tele-bridge).

Today I **saw red**. I was suspecting network, but after a quick audio test (Tools - Audio - Setup Wizard) it turned out its rather java audio issue. After some googling I found there is possibility to setup PulseAudio with OpenJDK. First of all locate your sound.properties file:

# locate sound.properties

Edit it and set javax.sound.sampled properties to PulseAudio providers. They are there already in Fedora 15 and you only have to uncomment it (and comment out the originals).



Now the important part - you need to rerun the Audio Wizard in Elluminate again and set the "default" input and output to start using PulseAudio plugin.

Elluminate is using fast and stable PulseAudio from now on. No delays, pauses or clicks any more. High five!

By the way there is cool audio/screen conferencing tool called Mikogo which is free to use. No Java needed, its fairly small and it is running smooth. Highly recommended.
