Why am I getting this LineUnavailableException?

Question

I keep getting the LineUnavailableException on line 34 of my code: https://www.refheap.com/21223

The error reads as javax.sound.sampled.LineUnavailableExceptio

Answer 1

the exception occurs when you try to open multiple data line at a same time. Second line blocks the opening of first data line.

Answer 2

I found the solution to the problem: the Beads audio library for Java. Simply amazing.
