I've deleted all other drivers except for snd_hda and sound but NVIDIA
interfaces also use snd_hda driver. Also, I have already set up
hw.snd.default_unit=4, which is the analog Intel interface (included in
my 1st mail). I'm not sure how I should choose the default device in
KDE, since it's chosen in hw.snd.default_unit. I'm not sure how you are
able to hear a "pop" when sound devices are detected because it doesn't
work that way on any of my other PC's (6 in total).
