After posting the above information to a corresponding bug in Skype, another user posted back a solution that definitely solved the problem for me for both VLC and Skype (and I suppose every other source in PC with intel-hda chipsets):

You have to modify the following line in /etc/pulse/default.pa

load-module module-udev-detect

with :

load-module module-udev-detect tsched=0

After further researches, I've found this is the suggested workaround for broken alsa sound drivers in regards to "glitch-free" PA. See following links for informations:
