[PlanetCCRMA] how to determine hw:0 is already in use issue

[Nicholas Manojlovic]

this may sound obvious.. but make sure you're not running any apps with
audio. (ie, mp3 player, etc).

also, disable arts in kde and the sound system in gnome (ESD I think). Hunt
around in the "Preferences" menu.

Your message is pretty common and I doubt your hardware is broken, only you
need to uncheck a few boxes.
