I guess this is a very long-standing known issue with CA0132 codec support. The codec driver, or more exactly, the given firmware blob, is very specific to some models (Chromebook Pixel, the old Creative CA0132 boards and some old Alienware machines), and the recent Creative models don't work with it well. There have been some struggles, but no good solution found yet. https://bugzilla.kernel.org/show_bug.cgi?id=111021 Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
