### AUDIO_INIT (40h) - Returns

If the audio device driver can satisfy the request as specified, it returns 0. If the request cannot be performed as specified, the audio device driver fills in the MCI_AUDIO_INIT fields with the supported values that most closely approximate the values specified by the user, sets the BESTFIT _PROVIDED bit in ulFlags, and returns 0 to the application.

Refer to the OS/2 Control Program Guide and Reference for more information on the return code for DosDevIOCtl.
