guys, you should realize that the ESS1868 codecs (and friends)
are extremely unfriendly to the programmer, and possibly
(according to Sanpei comments) broken in their handling of
auto-dma. As a consequence i cannot believe anyone wants to
write a driver for this chip fighting against all idiosincracies
of the hardware and its ugly design.
If you have a machine with that card, just replace it with a better
supported one. If you have a laptop with that card, well, you have
bad luck, but chances are that your laptop is already obsolete and
in 1yrs you will have to replace it because the battery has died, the
keyboard has broken keys, and the hard disk starts failing on some sectors.
Just be patient...
cheers
