One last thing,
I thought of was perhaps the headphone amp I own, here it is:

is balanced and the integrated amp (hitachi HA 4500) I own is not and that's why I am hearing the noise through it and not the headphone amp.
Just a thought..

Sure.  In your xorg.conf:

  Option "NoAccel" "true"


Most (all?) drivers accept that option.

Thanks guys, heaps. I tried the NoAccel option and even though it made using the computer almost unbearable to use it didn't help much with the noise. In fact I've bought matrox cards because they were reputed to be the best to use with Linux and Daws. I've been using this same board and card setup in the past for years and hadn't noticed the noise. What is strange is that I cannot hear the noise in my headphones (using a separate headphone amp and the same delta sound card) at all!! Absolutely quiet. So, I am hoping it must be an issue with this amp and setup.
I might make a cover for the sound card (used to modding stuff) and try and figure out how to get the drives and graphics card on their own irqs.
However, none of that will explain why there is no sound coming from the headphone amp.
I will keep experimenting, and thanks again for all your help.
Best, Nicholas
