sends illegal data to the unit, audio may not
be played back.

applications, the beginning of a song may
be muted when you switch between DSD

• Before you operate an audio playback
software application, it is recommended to
turn down the HP-A4BL audio output volume.

of an audio playback software application
have the same sampling rate.
