Current alsa_sound_last_init() was called as __initcall(). So, on current ALSA, only devices that had been properly registered at this point were shown. So, it will show "No soundcards found" if driver requests probe deferment. it's often misleading. This patch delays the timing of alsa_sound_last_init() as workaround.
