Humm.... I wonder, because speakers are off and noise doesn't come from 
them anyway. There is only two speakers on the top of the computer 
(harman-kardon) and they don't make any noise.

I've looked at KMS with the link you provided, but it seems rather hard 
to get it work ; a lot of things to do, and I'm not very good for that....

Thank you anyway
