It *looks* like you're trying to add a new clock source, but from the description this appears to be an externally visible clock which makes it very unclear why you have to guess the frequency. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
