if I remember all sound commands:
sound sound_name
music music_name
volume music 0 3000 (this will mute the music in 3 seconds)
volume music 100 3000 (this will make the music loud on 100% in 3 seconds)
volume sound 0 3000
volume sound 100 3000
music off
volume off
command sound will play it only once,
command music will play in a loop till you turn it off or change to another music
some sound and music can be played with both commands - some sounds how aver is not possible to use with music command - its necessary to test which work in the loop.
