This is a bit of a myth that seems to have been applied to all use of KS.
In fact, it is only true where the sound card doesn't expose hardware
acceleration (either real hardware, or host-based "hardware acceleration").
As long as the driver supports the creation of multiple streams then KMixer
gets its stream and each app using KS gets a stream too.  So on such
drivers, use of KS does not cause system sounds to be muted.
