[karmic] snd-ctxfi exhibits major static/crackling and repeated sound in all applications.

[anuraaga]

Using any application with sound on a stock Karmic install including the new snd-ctxfi ALSA driver for the Creative X-Fi results in crackled sound with a sort of echo (repeated playback of sound) that is unusable. Compiling and loading the old Creative ctxfi module results in working sound.
