Hi,The diagnostic trace you've posted indicates that you have both OSS (nm256_audio) and ALSA (snd_nm256) modules loaded. It is feasible that these drivers conflict, leading to the crash. Could you please try reproducing the problem with ALSA or OSS modules only? If they are loaded by hotplug, you'll probably have to blacklist one of the sets.
