Source data lines don't play the file when you open them, you have to manually read data from the AudioInputStream and write it to the SourceDataLine...and you're not doing that.
You essentially walked into the bathroom, lifted the toilet seat and unzipped your pants...and wondered why the toilet wasn't making that "I'm peeing" sound. It's because you didn't start actually moving urine from your bladder to the toilet...
