I had the same problem with a Delta1010LT. It was running great on 
Ubuntu Studio with a VIA MiniITX board that died on me. I replaced the 
mobo with a Jetway VIA Nano and installed Debian amd64 and I got the 
notorious hiss.
So I took the card out and now it's running in a WinXP box with no 
issues. So it's definitely not the capacitors. I think the sound of dead 
capacitors would be more like AC hum.
Might it be a PCI interrupt priority issue? I only have one PCI slot in 
the board so I couldn't test that.
