Hello
on my system the hda_intel sound card produces static noise after the
driver is loaded until the control
misc.input-mix-mute1
is changed. Regardless of its state if it is changed after loading the
driver the noise stops.
The obvious workaround for this issue is to save the state of the
control as muted so that the restore scripts mute it shortly after the
driver is loaded.
However, it would be better it the driver initialized the card so that
it does not make noise.
