Sounds are audible in the speakers at low level which sound almost like
instability, but which vary with hard disk activity. Muting the sound with
Kmix stops the noise.
Can I block these sounds with suppressors, or similar? I don't have any
ferrite suppressors handy at the moment.
Audio interference from nearby chips is quite common. Using a digital
(optical or coax) output should get rid of the noise.
Such an option is often not available. AIR, what solved the problem for
me (or worked around it, one) was hdparm -u "get/set unmaskirq flag
(0/1)". But it's been years so ICBW. There might be /etc/hdparm.conf
in your distro but its structure is left as an exercise for the reader.
