I tried to look into the dts file and the code but i am afraid this is a bit too high for me. I can say that the analog output works, even at high sampling rates. And I have read something about a clock source could be the problem. I'm sorry I can't tell you any more. mfg Markus _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
