[ltp] R32 making awful noise on microphone channel

[Stephan Herhut]

Hello,

I am using a R32 with built in wireless (prism II). When I activate 
(unmute) the microphone channel, there are strange "knocking" sound 
coming out of the speakers. As you might guess, these sound make things 
like netmeeting/gnome-meeting unusable, as these sound are also sent to 
other members of a meeting. So is this a normal behaviour or should I 
send my ThinkPad to repair, again:(

Besides, when using Acrobat (windows and linux), there is a very high 
noise coming from somewhere inside the ThinkPad.

Maybe I am just going mad?

So if anyone has the same expriences...

Stephan
