Hi,

ac97c_alsa.c is the result of the 2 patches I have send to the alsa 
mailing list 
(http://mailman.alsa-project.org/pipermail/alsa-devel/2010-March/025709.html 
and 
http://mailman.alsa-project.org/pipermail/alsa-devel/2010-February/025628.html). 
It indeed adds support for AT91(1/2) and full duplex(2/2).But is is 
strange that if you only apply only the first patch you encounter errors...

On my side I have only tested these patches with mplayer and aplay.
Plus to test the full duplex I have done like this:
"arecord -d 10 -f cd -t wav test.wav & mplayer my_file.mp3"
