sound card issue, need advice...

[bluedane]

I have a laptop with an Echo Indigo IO. Worked great while I was on the road. I recently hooked it up to some monitors and realized that I have HORRENDOUS noise coming out of the Indigo - every time the hasrd drive reads, every time I move the mouse - anything. Completely unusable. I must have some crappy headphones or something to not have heard this stuff.

I have a theory that I am getting all of this noise because the A2D on the Indigo is *inside* the computer and thus subject to its analog noise from the hard drive.

Here's my question. I also have an Echo Mona. I could buy the laptop card for it which would send a pure digital signal out of the computer and do the D2A elsewhere. If mytheory is correct, I would have a beautiful signal again. If it's wrong, I'm throwing good money after bad. What do people think? Echo wouldn't commit to anything.

I also have a Mona that, while getting old, is still good.
But instead of investing on a discontinued piece of hardware like that, maybe it is better sell both Indigo and Mona now that they still have a certain value and buy a new firewire interface.
