Audio updates
Sound playin' code now makes sure the volume is a number, falls between 0 and 1 (inclusive) and sets it to 1 otherwise.
Sets the volume to 1 if it's not a number or the volume is not specified, and makes the volume range fall between 0 and 1 inclusively if it's greater or smaller.
The FINAL update??
