Title:
Background hissing sound even when volume muted
Status in “alsa-driver” package in Ubuntu:
New
Bug description:
Problem also occurs on the front headphone jack, and when using
different headphones. 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.
