21 This driver should provide support for most Aztech AZT2320 based cards.
22 Several AZT2316 chips are also supported/tested, but autoprobe doesn't
23 work: all module option have to be set.
25 No docs available for us at Aztech headquarters !!! Unbelievable ...
26 No other help obtained.
28 Thanks to Rainer Wiesner <rainer.wiesner@01019freenet.de> for the WSS
29 activation method (full-duplex audio!).
