Re: full duplex audio

I'm 99% sure the ucb1400 supports full duplex, and the ac97 linux  
driver shouldn't have any problems with reading and writing at the  
same time (well, time-sliced).  The driver yields to the scheduler  
while it's waiting for data on the ac97 link, so userspace apps will  
get the opportunity to keep the buffers full.
