I must own an inspironingly cheap one. Say so there is absolutely no
software way to get rid of the singing capacitor? That's pretty much
what I assume it to be. Singing capacitor caused by the interrupts at
the end of each buffering cycle. I only have a vague idea what that
means, but maybe you kernel people can help. Please?
No, there's no possible software fix for this hardware problem.
If you are extremely lucky there might be...
Capacitors will only sing when the current through changes rapidly, so
if you can make sure your current consumption remains constant it might
be better.
Some things you can try:
Disable all power management features and run on full power with lots of
load.
or
Disable all power management features and fix your cpu speed to the
lowest setting.
There is a (very) small chance that this will help.
