The audio status field indicates the status of an audio play operation. The
audio status values are defined as follows. Audio status values 03h and 04h
return information on previous audio operations; they are returned only once
after the condition has ocurred. If another audio play operation is not
requested, the audio status returned for subsequent READ SUB-CHANNEL commands
is 05h.
