The user space does not handle bitfields for controls, it uses integers. The driver must therefore present the controls within the hardware as integers to user space. I thought he was having problems because the translation was not being done in the driver, so user space was handling the value wrongly. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
