Thanks for the info, Jaroslav. I upgraded all of the lib, driver, tools, and utils to 1.0.4rc1. But I got the same results: linux rec command worked fine but arecord caused Segmentation fault after readi_func was called 3 times (aplay also worked alright). Any idea what can be happening? Or is there anybody using the same card (Audigy 2 NX) without problem?
