(6)
Important notice for Mac OS X 10.9.x or newer.
MacOS X 9.x or newer set this sample rate to 705600 Hz at the first time, but KEB03
does not support L-PCM 705.6 kHz. This sample rate must be set below 384000 Hz prior
to start playing back music.
If sample rate which is not identical to the sample rate of original music file itself is selected,
MacOS X Audio driver will execute sample rate conversion. As this conversion will affect
audio quality, we recommend to select adequate sample rate which is identical to one of
music file at this field.
