Stay out of /lib/modules.
The file you want is /etc/modprobe.conf.

The file is only consulted when a module is loaded - if your sound
modules are already loaded then changes to the file have no immediate
effect.

Sure, but make sure you keep a copy of the original file before you change
it. That way it is easy to revert.

Depending on the kernel and modules you may need to reboot between tests
(modify file, reboot, try skype, lather rinse, repeat). In principle you
don't need to reboot, but my module fu is weak.

Also, a reboot is a "full test" in the sense that you are testing how the
machine will behave "from scratch", which you need to know anyway.
