To get all apps to use it set a pcm.!default

Personally, I find using pulseaudio to manage it (moving streams etc)
to be much easier. BT headsets run out of battery, if that happens you
have to manually change .asoundrc and perhaps restart sound-generating
apps, if you're not using a sound server such as pulseaudio.

If you want to read up on the different sound components, just do a
google search. There's tons of articles out there, some very good,
mostly a bit crap. Lennart Pottering (dev for Pulse) has a
particularly good one I recall. Most on Arch wouldn't like his
conclusions though.
