Now I am stuck on what ought to be a very simple problem: What "option"s can be given to my own driver (or generally any alsa driver)? My own driver appears to be snd_intel8x0, which is documented at http://www.alsa-project.org/main/index.php/Matrix:Module-intel8x0 Unfortunately the "parm:"s (supposing these the possible arguments to an "option" statement in modules.conf) don't seem to include all possible options to be applied to this module.
