I logged this exception:
1  
2  
java.lang.IllegalArgumentException: No line matching interface Clip supporting format PCM_SIGNED 22000.0 Hz, 16 bit, mono, 2 bytes/frame,
little-endian, and buffers of 4610 to 4610 bytes is supported


that was on:  Linux 2.6.32-22-generic   java 1.6.0_18
Could it be that no sound card was available?
Do you think it is worth checking which formats are available? (and how do you do it?)

I decided to just not care and disable sound if that exception occurs.

Here I realized that 22050 is more common than 22000, I changed the frequency and hope it'll help.
