It's just not reasonable to restrict access to the audio hw
Having format converters and sample rate converters in the kernel is scary. Straight mixing is doable, but that means that every app accessing sound has to be using the same format, likely the best the sound hardware can support, i.e. 48kHz 16bit 2channels for most current hardware. While this may not necessarily break the OSS API, it will break many current OSS apps. And yes, no mmap
