38 * HDA mixer sink definition (ring-3).
39 *
40 * Its purpose is to know which audio mixer sink is bound to which SDn
41 * (SDI/SDO) device stream.
42 *
43 * This is needed in order to handle interleaved streams (that is, multiple
44 * channels in one stream) or non-interleaved streams (each channel has a
45 * dedicated stream).
46 *
47 * This is only known to the actual device emulation level.
