Weird beeping from inside notebook

[muellkontrolle]

Hi there,

I get weird beeping noises from my IBM T23 (PIIIM, 1.2GHz) - but only
when certain applications are loaded. I noticed the beeps from under
the left palmrest when one or more of the following apps are loaded,
even when in the background and completely idle:
- Trillian or Skype
- Flash-enabled websites
- Windows Media Player

No beeping with IE, Office, Movie Maker, Mozilla

I'm running XP Pro SP2. Someone suggested that this might be
SP2-related. I will further investigate this with a clean install
without SP2.

When Speedstep is set to "Adaptive", the beeping is related to any
activity on the laptop, i.e. moving windows, clicking a link in my
browser etc. loudens the beeping.

The beeping is more obvious when running on AC, as the CPU runs faster.
On the slow and very slow setting, it is more silent.

What could that be? It doesn't seem to come from the speakers,
attaching headphones or muting them doesnt help.

You can follow the same issue here:

Any help would be greatly appreciated

By reading the specific programs/applications that either do or do not create
beeps, you have listed ones that utilize the soundcard which are probably the
cause. Programs that do not use media do not cause beeps. Thus............
the beeps could be the fault of the soundcard. My prognosis.... :~)

Then, disabling the audio driver should change the beeping - but it
doesn't

The beeping doesn't occur under Linux, so I guess it should be
driver-related.
