The PLAYBACK CONTROL command requests that the target set the audio playas
specified.
If the drive is not in the ready condition the command will be terminated
with a CHECK CONDITION status. The sense key will be set to NOT READY and
the appropriate additional sense code set.
The parameter length specifies the number of bytes of data to be sent during
the data out phase.
