Channel 0 is an auto-allocate channel, the others override anything
|

already running on that entity/channel pair.

An attenuation of 0 will play full volume everywhere in the level.
|

Larger attenuations will drop off. (max 4 attenuation)

Timeofs can range from 0.0 to 0.1 to cause sounds to be started
|

later in the frame than they normally would.

If origin is NULL, the origin is determined from the entity origin

or the midpoint of the entity box for bmodels.
