olem.audio_wait_end_of_playback()

# Le mettre en pause pendant 2 s
olem.audio_play_file(SOUND)
olem.delay_ms(1000)
olem.audio_pause()

olem.audio_wait_end_of_playback()

# Baisser le volume pendant qu'il est joué
olem.audio_play_file(SOUND)
olem.audio_volume_enable(True)
for i in range(10, 0, -1):
    olem.audio_volume_set(i / 10)
    olem.delay_ms(200)
