|

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 <rainer.wiesner@01019freenet.de> for the WSS
|
|
activation method (full-duplex audio!).
