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.
