AudioSystem.getMixerInfo() will not return null, so we don't have to …

[HelgeStenstrom]

…check for it.

Description

Null checks clutter the code, and should be removed when not needed. AudioSystem.getMixerInfo() will not return null, so we don't have to check if it returns null. AudioSystem.getMixerInfo() may return an empty array.
