In my analysis this is a limitation and we can't do anything more, let me know if you are aware any alternative solution for this.

@Renjithkannath Please, add this evaluation to [JDK-7116070](https://bugs.openjdk.org/browse/JDK-7116070). The bug itself can be closed as *External*: we can do nothing about it, it's a limitation of Windows API.

If Java migrates to a newer audio API, JDK-7116070 will be resolved.
