You bet me too it ^^
But i think it's this next bit, where i've pointed using the // added again.

my outcome is this
CardRemoved
fadeoutMP3
CardRemoved
0002.mp3 // placed card no sound is played
NewCard 0x0A 0x97 0xF3 0x16
CardRemoved
fadeoutMP3 // fadeout function works sound fades out.
CardRemoved
0002.mp3
NewCard 0x0A 0x97 0xF3 0x16
CardRemoved
fadeoutMP3
CardRemoved
fadeoutMP3
CardRemoved
fadeoutMP3
CardRemoved
I will be adding other cards too, but only another two ^^
