/*
    This driver should provide support for most Aztech AZT2320 based cards.
    Several AZT2316 chips are also supported/tested, but autoprobe doesn't
    work: all module option have to be set.

    No docs available for us at Aztech headquarters !!!   Unbelievable ...
    No other help obtained.

    Thanks to Rainer Wiesner <[email protected]> for the WSS
    activation method (full-duplex audio!).
