Dang reply-to-all....<br><br>You are talking about two separate problems.<br><br>One is a ground
loop(The point where playing from battery makes a difference) and the
easy solution is to lift the audio ground(NOT the mains ground).<br><br>The
other is poor internal shielding. Typically a problem with built in
audio interfaces. There isn't a good solution other than to bypass the
interface. While ADAT is certainly an option and moving the D/A
outside of the box will make a difference, how much of one will depend
primarily on the quality of the interface. For built in interfaces on
laptops it will likely be noticeable. For higher end cases though it
might not be as much. Considering however these days the standard
seems to be to have a breakout box anyways connected either via
Firewire, USB, or PCMCIA/Expresscard, it is kind of a moot point with
the higher end stuff nowadays anyways.<br>

</div>Usually helps, or playing from batterys but I experienced and know<br>
further cases, where even that doesnt helped. Hence my statement the<br>
only predictable way is going optical (but also the most expensive).<br>
