Its independent of volume and on headphones. Yes, its general whining
stuff, and does change with processor load, and drive access as far as I
can hear. I have moved some leads about and its less now, but still audible.
Obviously the psu is a heap of junk. If I could see I'd go in and put
capacitors all over the place!

I had to put a new psu in a machine over the Christmas,
and now notice the bog standard Soundblaster live card
seems to be outputting a kind of gurgling whine which
varies and kind of sounds likt e sort of low level

Two probable causes:

(1) Bad grounding of the buses on the system board.

(2) Bus domination. You need to follow up and find out what is changing
that correlates with the noise. One possible such source would be the hard
drive or the mouse. Problems that track the mouse trace back to the video
card. Problems with bus domination by hard drive controllers and video
cards can sometimes be addressed via BIOS and driver parameters.

If grounding is the problem, then there is a possibility that floating the
analog audio output of the audio interface might help. To evaluate this
see how the card sounds with just headphones plugged into it.
