Re: Problem with arecord on Audigy 2 NX

[Yitao Duan <duan@cs.berkeley.edu>]

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?

Thanks.
