Userspace should not be involved in suspend/resume. Having in-kernel equivalent of alsactl store / alsactl restore might help alsa driver authors... And might be enough for suspend-to-disk to +/- work. (Well, unless sound was playing when user requested suspend, that one needs proper support). Pavel -- When do you have a heart between your knees?
