Anyway, that suspend-on-idle module is more for battery-operated devices (laptops) and not real significant in a media center, so I commented out the load line and I no longer miss the beginnings of sounds.

As is often the case, the archlinux community has
a prefered/recommended/better fix (which involves
a user override) documented at:

https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Pops_when_starting_and_stopping_playback

No matter your opinion of the archlinux distro itself,
their documentation, especially around the desktop
experience, is a really excellent resource.
