### MCI_AUDIO_CHANGE Field - rOutputList[8]

rOutputList[8] (MCI_AUDIO_DEVID) Output devices are specified using an array of MCI_AUDIO_DEVID data structures in the rOutputList field. Unused entries are set to NULL_OUTPUT. The MCI_AUDIO_DEVID structure permits device specification by type and ordinal number (for those audio adapters that support more than one device of a specific type). For example, to specify stereo line output, set:

    rOutputList[0].ulDevType = STEREO_LINE_OUTPUT

    rOutputList[0].ulDevNum  = DEVICE_1.
