-20-bit and 24-bit I/O formats.
-The machine-independent audio layer supports samples with 32-bit precision,
-but these will be converted down to 16-bit before output, because converting
-to a hardware precision that isn't a power of two is not yet handled.
+Hardware formats higher than 16 bits precision.
+Since the machine-independent audio layer converts all input from
+the userland and the hardware layer to 16 bits precision for processing,
+so there is no (or few) merit to support them.
