The only time caps in a computer would give you ac hum problems would be

Also, it may not be *those* capacitors, but it could very well still be
capacitor related.
A *well* designed mobo has them dotted all over the place, seemingly
redundant and in parallel. There are also additional ground plane
'capacitors' formed in the very structure of the board itself.
Personally I've not had very good results with VIA mobo's - all sorts
of obscure problems, especially with the micro and nano boards.
Now if the card's filtering is not 100% and the mobo's isn't either
that could be the cause of your problems.

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. I'm getting closer to testing my new Delta
1010.
Are there any more reports of problems with the device?
I'm hoping there won't be. Hearing that some people get a "hiss"
noise is scary.
I'll be tracking 2 angles tomorrow with my hiss problem: 1) put the
card in another computer and; 2) failing (1), opening up the case and
checking capacitors. I've been reading a bit this week about burned out
capacitors.
... more tomorrow after I get my hands dirty.
Might it be a PCI interrupt priority issue? I only
have one PCI slot in
the board so I couldn't test that.

Always possible of course but it seems likely that interrupt clashes
would be more likely to cause drop-out crackles.
