Interesting question as I use a laptop right now with and internal sound 
card and if I can see the trace the DM780 will decode it unless there 
are strong signals close by.  Then I tighten the filters down and 
usually it comes in clean.

Maybe the number of bits in the sound card make a big difference but I 
dont know how to check this.

Also what filters do you use,  I am on the fence regarding a 500 hz or 
700 hxz 8 pole to add to the system.
