My audio won't work for Webex


I was listening to a presentation in webex for over half an hour when the audio quit. I could stop the audio and restart it and it would work for 2 seconds and quit again. Audio works for my other apps, such as Rythembox, mplayer, etc.

Here is what I have:
Ubuntu 10.10, Gnome 2.32.0, Alsa audio, Sun Java plugin 6.22, Adobe flash plugin 10.1

Any help appreciated.

are you sure you got ALSA? doesn't Ubuntu 10.10 ship with PulseAudio? I'd love to know this, so could someone post.....?

Hi, I know it is a little bit late but I had a similar issue. In a Webex replay, I would hear the sound for 2 seconds and it would stop.
Pressing pause and play would do the same. Brief sound then cut. Unmutting and mutting the presentation also gave me some sound.
I'm running Ubuntu 11.04, with sun java. The only thing I did was to install libstdc++5 (sudo apt-get install libstdc++5).

I restarted my Firefox 4 but it was NOT enough. I had to reboot.

WebEx is only partly Java. The AV code is Windows or Mac specific, so I don't think this kludge supports Linux. I can't believe people actually pay for WebEx when there are some alternatives.

I've been struggling with this for a while, Webex is not very Linux friendly.

Here's what I did to make it work on Linux Mint 13 (Maya) 64-bit:
1. Install 32-bit libraries
# apt-get install ia32-libs
2. Download Firefox 32-bit. I got mine here:
http://releases.mozilla.org/pub/mozi...st/linux-i686/
(that link worked yesterday, but today it seems dead, posting for reference)
3. Download Java JRE 32-bit from Oracle. I followed the instructions on this page:
https://www.java.com/en/download/help/linux_install.xml
4. Extract the Firefox tar to a folder, say /opt/firefox32
5. Extract the JRE to another folder, say /opt/java32
6. Backup the existing Java plugin for Firefox, in my case (found this folder by starting the normal firefox from command line, and checking which library was listed in the errors when running Webex):
# cd /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64
# mv IcedTeaPlugin.so backup_IcedTeaPlugin.so
7. Create a symbolic link to the 32-bit Java plugin:
# ln -s /opt/java32/jre1.7.0_45/lib/i386/libnpjp2.so ./IcedTeaPlugin.so
8. Start 32-bit Firefox:
# /opt/firefox32/firefox/firefox

Now not only does Webex start, both the microphone and the speakers are working too.

I wrote a small script to create the symlink, start Firefox and upon exiting Firefox restore the files back to default. This way I don't have to interfere with my normal Firefox install, and only launch this when I want to use Webex. The only downside is I have to close all open Firefox windows first.

I usually just nuke ~/.webex when mine starts "acting up".
