    If you read Documentation/sound/es1370.txt, you'd know
    that it doesn't implement ALaw and uLaw, because the hardware
    doesn't support these formats and due to the mmap interface
    converting sample formats in the driver is infeasible.

    Besides it announces not being able to play these formats,
    apps should check the return values from ioctl commands.
