=================

Start playback of a sound, loaded into the static portion of the channel array.
|
|
Currently, this should be used for looping ambient sounds, looping sounds
|
|
that should not be interrupted until complete, non-creature sentences,
|
|
and one-shot ambient streaming sounds. Can also play 'regular' sounds one-shot,
|
|
in case designers want to trigger regular game sounds.
|
|
Pitch changes playback pitch of wave by % above or below 100. Ignored if pitch == 100
|
|
|
|
NOTE: volume is 0.0 - 1.0 and attenuation is 0.0 - 1.0 when passed in.
