Sounds like a failing componant, generally a capacitor. They except a certian amount
of "noise" in the manufacturing processes today. These componants are so small and
surface mounted that failures are not uncommon. Problems with the larger "can" capacitors
are also a good possibility for bleeding noise into the power circuits. Same thing
happens in the "modern" audio processing equipment that I buy and use today unlike,
15 years ago when most manufacturing processes and design didn't use much surface
mount technology.
The only motherboards/sound card combo's that I have heard that were totally quiet
of digital noise are the prosumer sound cards on a server class motherboard (I use
these type systems for reprocessing audio sources, audio workstations in other words).
The built in sound on the motherboards I have built for customers have all been
relatively noisey if you turn up the volume high enough. (even on $200 plus motherboards)
If you tried another pair of speakers and heard the same noise, or tried the same
speakers on a different system and didn't hear the noise, I would guess that narrows
it down. :-(
If nothing else has changed, like cable changes, repositioning the computer or speakers
etc, I would lean toward a componant on the motherboard getting weak. It may not
get any worse over the life of the machine, or it might. Just have to keep an "ear"
on it! ;-)
In the worst case if you start getting weird shutdowns or crashes, that generally
points toward a failing board and may be linked toward the noise, as in the power
portions of the board are failing. (note.. the old defective capacitor issues around
6-10 years ago, that still happen today, but less frequently)
