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