Hi Richard.

Try putting ferrite cores on the leads to the speakers at each end of the 
interconnecting cables.  Most of the computer speakers have a very high 
degree of amplification, a lot of lead length that acts like an antenna, 
and almost no shielding.  It's a pretty bad combination.  You might also 
consider winding the power cord around a ferrite core.  I esxpect that 2 
meters you would only need a few turns of wire to choke off the RF pickup.
