I have got Ubuntu 12.04 on an EeePC netbook.
All works fine.

However, I want to make a web conference, as a speaker on

To set it up, it popps up the Adobe Flash Player Setting's little window... and then it is blocked. I cannot make any clicking.

I spoke with their Support, and they tested it, and said, it was a system problem, with my Ubuntu.

Please, help. How may I make my mic work?

Btw, I can well participate on webconferences there... as a listener. I hear well, and I can ask questions well via the chat function.

However, no talking.
And my videocamera is not working, either.

What to do?
