Why, because you love test/sample programs of alsa-lib that much? Quantify the number of users that might be running the test sample programs of alsa-lib versus the amount of effort it will take to add the ioctl to the audio device. Oh, and please also quantify the additional code bloat and possible interactions with other functionality. Do you have any clue of the details? If not then I would say your anger is misplaced. There is such a thing as return on investment that everyone has to decide. In any case, the kernel is open, download it and add the ioctl required. Frank
