Sorry, it was clear in my head :) The last case was "when using the two audio controllers with different sample rates" (I should have added "in the set [44.1, 48, 96 kHz]"). Then, with or without the availability of external clocks, both controllers will set the unique DCO to two different rates. -- Ken ar c'hentañ | ** Breizh ha Linux atav! ** Jef | http://moinejf.free.fr/ -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
