I got "The Audio Device is Unaccessible Now" when trying to connect audio to WebEx session using computer. It's known issue for 64-bit installations and common workaround is to setup 32-bit browser and Java. It works, I saw it by myself. But I got the same issue on Ubuntu 12.04 LTS 32 bit.

Firefox 16.0.2 (Mozilla Firefox for Ubuntu canonical - 1.0) or Chronium Version 20.0.1132.47 Ubuntu 12.04 (144678) - does not matter. Java(TM) Plug-in 1.7.0_09.

Java 7 - Oracle 32 bit: java -version java version "1.7.0_09" Java(TM) SE Runtime Environment (build 1.7.0_09-b05) Java HotSpot(TM) Server VM (build 23.5-b02, mixed mode)

Does anyone know what could be wrong? Thank you in advance.

Last evening I ran in the same trouble. Ubuntu 12.04 with OpenJDK 7. I had no error message but the incoming audio was mute or only working for a few seconds. I figured out that it seems to be a problem with the alsa plugin for java and pulseaudio. After removing pulseaudio like in these link

it worked fine.

Maybe these topics are related with this problem

but this is far above my understanding.

Hope this helps, Tobias

I don't think this is the same problem. – Tal Weiss Jun 30 '13 at 13:48
if you do remove pulseaudio I imagine you'll break all sorts of useful things, such as having two apps playing sound at once. – Tim Abell May 9 at 13:34

Fixed by latest WebEx software update

You should probably accept your own answer as the best one, as the issue got solved. – papukaija Jul 17 '13 at 9:14
I still have the problem on the latest ubuntu / webex – Tim Abell May 9 at 13:35
