Fix a problem introduced with the SSBM fix - Sometimes when a music stream ended sampleEnd

would become extremely high and the game would play random sound data from ARAM resulting in

a strange noise. This should take care of that. However, when you leave the Continue menu there's

some kind of buzing or interference noise in the music. But it goes away, so I guess it's not a
