microphone audio level problem with flash.

[Andrea Greggio]

Hello, I installed openmeetings on a virtual server and use an EEPC with 
ubuntu 11.10 and firefox  with client.
The system works, only that the Adobe Flash plugin has a bug and does 
not allow you to adjust the microphone volume on the webcam because not 
once open the settings you can not press ok.
So the audio captured remains low, even when the volume of the system 
does not change the result.
There's a way to adjust the volume level of microphone in openmeetings?
Has anyone had the same problem with firefox + flash on linux?
