Comment 4 for bug 688991

Object:
Reported bug : microphone is always "mute".

Ubuntu Team, or Community,

Firstable, you I must confess as you will realize I am a beginner in Ubuntu.

I upgraded Maverick (10.10) to Natty development branch (11.04). The update was OK except the microphone of my laptop had trouble. It does not work any more.
I tried to install applications via "the Manager of Synaptic Packages". I've got a French graphical interface, so sorry for the supposed translation.
Afterwards I launched the "Application/Ubuntu Software" thus the bug appeared.
My computer features using "sysinfo" command :
