Probably you're missing code to register the SSC device in your board file, you should be calling add_device_ssc() somewhere in your arch/arm code and ssc_request() in your machine file. > It looks that this message comes from snd_soc_register_dai in soc-core.c > if (!dai->dev) > printk(KERN_WARNING "No device for DAI %s\n", dai->name); > it seems for some reason it thinks there is no device in dai->dev Yes, the reason for this being that the Atmel driver currently doesn't make any effort to initialise the device. At the minute that's purely a cosmetic error. Before it becomes an actual problem the drivers will be updated to fill in a device. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
