If it were me I would "apt-get remove --purge alsa-utils alsa-base knx-alsa" before anything else. And I think you're better off just compiling the drivers yourself. I promise it's not hard if you follow the instructions on the ALSA page specifically for your card. And in the link I posted before, the libasound2, alsa-utils and alsa-base packages are all specifically made for the 1.0.2c driver. So you won't have to worry about mismatching there as long as you get and compile that driver release. It's worked for me...so I know it can work for you. And I don't think you've done any real damage by apt-getting those things. Just remove and purge them and then try again...this time compiling the drivers for your card.
