Subject: High pitched sound with 2.6.15-ck1 --  Update info
Date: Sat, 28 Jan 2006 01:05:44 +0200	[thread overview]
Message-ID: <200601280105.44804.gkanis@cems.umn.edu> (raw)

Hi,

I had some free time and I was switching from one C-state to another to check 
when I hear this high pitched sound, I discover the following:

When the system is in the C4-state I hear this high pitched sound only when 
the USB-mouse is plugged in!  If I unplug the mouse, the sound is not audible 
anymore. If I plug in the USB-stick the sound is not audible!  I did some 
experiments and I found that when the system is in the C3 or C4-state, I hear 
the sound only when the USB-mouse is plugged in. On the other hand, in the C1 
or C2-state the sound is not audible regardless of whether the USB-mouse is 
plugged in or not. 
I see a similar behavior in windows, but the only difference is that the sound 
is not audible when the USB-stick and the USB-mouse are both plugged in!

Does anybody have any idea why this is happening?

Thank you,
Vasilis
