Although I have only seen this on capture, another possible reason for this is due to the way the SSI registers are setup on the MX27. Eric Bénard's patches that are in the latest kernel fixed a similar problem for me. The eukrea audio machine driver was a good reference. randolph _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
