I have a real conundrum for the gurus out there. For a while I have been annoyed with this crackling sound from my loudspeakers, as if you jiggle a broken cord. The strange thing is that it happens in intervals of exactly 1 minute and lasts for maybe 3-4 seconds.
I changed the setting on the computer clock, but the crackling sound continued according to original schedule, as if to some external clock, with exactly 1 minute in between.
My sound card is Creative Sound Blaster X-Fi Xtreme Audio.
This has be completely baffled, anyone have any ideas?
