Hi Igor. The proper way to unload the alsa modules is modprobe -r snd-emu10k1 in your case. This should force unloading of the complete module stack. In other words, you unload your primary sound module, and the rest of the stack is handled automatically. For the 2.6.x kernels, you also need a package called module-init-tools or something like that. Someone please correct me if I have the package name wrong. Anyway, it's a special set of module handling utilities for the 2.6.x kernels. Look at the CHANGES file in your kernel source tree for more information. Gene
