record problem

[Adel ESSAFI]

dear all
I have a poblem with recording sound. My sound card is intel
Multimedia audio controller: Intel Corporation 82801FB/FBM/FR/FW/FRW 
(ICH6 Family) AC'97 Audio Controller (rev 03)

and I am using krec (kde). I dont succeed to record my voice (and then 
using skype and so on).
what is the recorder of gnome Desktop and is there any configuration to 
do. Note that I am listenning to the music without problem.
Thank you for help
Adel
