Confirming the popping, it occurs less frequently, only when the sound
card is activated after having powered down.

Far more annoying though is an extremely high pitched "hissing" sound
(for lack of a better word), that starts whenever the card powers down.
My father cannot hear it, (he is approaching 55yrs) but the rest of us
hear it clearly. It might be static gathering because I don't tend to
notice the sound until the computer has run for a few hours.

so far it seems both pop and hiss are fixed by the workarounds, either
in /etc/modprobe.d/alsa-base.conf or /etc/pulse/default.pa (as suggested
by #50)
