                 AuFormatULAW8,          AuFormatLinearUnsigned8,          AuFormatLinearSigned8,
                 AuFormatLinearSigned16MSB,                          AuFormatLinearUnsigned16MSB,
                 AuFormatSignedLinear16LSB, and AuFormatLinearUnsigned16LSB.

       flow      If non-NULL, returns the flow ID.
