When I switched into KDE desktop, just began the peripheral
initializing, can hear some static noise coming up from left speaker,
finally get into KDE desktop, the static noise remains and even when the
mouse scrolls, can hear extra scrolling noise being generated.
In the terminal I entered the "gnome-volume-control", found that on the
volume control panel, the " Digital-1" was set at max position, I
checked mark the mute and the noise is gone and everything is back to
normal. However this new setting can not be stored ( I tried alsactl
store, but won't work), log out and then log into KDE desktop again,
same thing will happen again. Any one can suggest a fix for this annoyance?
