Sound cutting out constantly.

Or better just switch to e.g. OpenAL.
Its pretty dumb to handle audio buffers in java. If the buffer size is less than pauses caused by the garbage collector the audio will be choppy. For example when going through doors this pretty much always happens.

Enjoy your audio latency of 170ms!

I found the best solution: turn sound off.
