The volume of the static noise also increases whenever I perform some action, e.g. clicking a tab, inserting a usb key or compressing/uncompressing a tar.gz archive. There is also a consistent pulsing superimposed on the background static noise. Modifying /etc/modprobe.d/alsa-base.conf with various options for snd- hda-intel have had little or no effect, and adjusting the sliders in alsamixer have also proved fruitless.
