alsa, oss, pulse (how to switch?)
I have been reading a lot about using different audio output methods, among them are alsa (the one my mpd defaulted to,) pulseaudio, and oss4.
First off, what are these things? Are they a top level interface to my sound hardware? or a low level driver for it?
Can I use just any one I want?
How does it (they) know what kind of sound card I have in my machine? Do they care? Are all sound cards enough alike that there is no difference?
If I want to try to use Pulse vs. alsa, what steps must I go through to archive that? (download drivers, install codecs, replace my sound card?)
Thanks for helping a dimbulb here,
