Hold on. It is supposed to be done in a backwards compatible way
already. Before all card varients we handled as being the same card,
except for a few special cases. The first version of the patch took the
general case and named it "Audigy Unknown" and gave it the correct
parameters as were used before in the general case of all card varients
being the same. Then, I looked through the code, and extracted all the
special cases, and created specific recognition of those cards and set
the correct feature variables, so they were also handled.
The result of this should have been that there were no performance
change between either versions. Then, as more card types were
identified, I added special cases for them, but in their case, they used
all the default parameters for the general case, the only difference was
that the correct Model name was recorded and displayed in
/proc/asound/cards. This is mainly just to help users identify their
particular card, without having to remove the case of their PC. So this
helps them report bugs better.

If there are loss of features during the upgrade, I would be very
suprised. I suspect that the same problems one sees now with some cards,
has been there all along. If that is not the case, please report them in
the bug tracker in the normal way.
