System power rail noise is not being effectively filtered
out of your audio (card or motherboard-audio).
While it can sometimes be a poor power supply itself, it can
be far more common from typical cheap motherboard-integrated
sound and so the solution is to replace the onboard sound
with any halfway-decent sound card. A cheap sound card
might provide same relief, but IMO it's better to get an
older halfway decent card than a really cheap new one- at
about same price-points at least.
Others have claimed disabling ACPI power management has
helped but I have no further info about this, only
repeating that rumorl. I do know that replacing the card is
sometimes necessary and solves the problem.
You might also try muting any unused analog audio inputs
(using Windows'/other operating system audio mixer or the
sound "card's" audio mixer software) to see if it reduces
the noise to an acceptible level.
