<div class="moz-cite-prefix">if it's laptops, try to remove the
power supply of the 2 computers to see if the noise is still here,
you can then remove the ground from the electrical socket (power
strip ?) and replug the power supply<br>

hey !
<div><br>
</div>
<div>so I have a weird problem here</div>
<div><br>
</div>
<div>On one laptop I had no line in, so I bought a behringer
UCA202 wich is a line in to usb.</div>
<div><br>
</div>
<div>Now when I use it, in pure data, or audacity, but i'm
sure other softwares,</div>
<div><br>
</div>
<div>it's working fine untill I plug the laptop to another
laptop with just a RJ45 cable, no box.</div>
<div><br>
</div>
<div>As soon as the computers are connected, I have a terrible
noise ... it's quite low, but it's very anoying.</div>
<div><br>
</div>
<div>Somebody ever had this problem ?</div>
<div><br>
</div>
<div>cheers</div>
