How to use sound

For one time sounds:

sound sound_name

For looping sounds (usually for music):

music sound_name

To turn off the sound/music

sound off
music off

For volume:

volume sound x T
volume music x T

x is volume level 0 to 100
T is time in milliseconds (1000 milliseconds is 1 second)

An example would be:
music music_fashionedge
volume music 50 2000
