Hi to all!

I have installed Kalyway 10.4.10 on my dell, but the integrated sigmatel 9227 didn't work, so i tried with a creative ct4810 with the kXAudioDriver1.2b0... It worked for 10 minutes then the sound began to distort! I tried with MaxxussAC97AudioES137x.kext but now OSX doesn't recognise my card...

1-how can i uninstall the Maxxuss' kext?
2-is there a solution for the distortion of the CT4810?
3-which cheap card can i buy?

Thanks and sorry for my english!
