Thanks for the quick answer. I had a look at these patches, but I don't
think that the solution to my problem is that similar. As far as I can
see the sound hardware is registered correctly in our platform code.
I've added some printk() statements to verify that this code in
raumfeld.c is indeed run at bootup:

	raumfeld_audio_device = platform_device_alloc("soc-audio", 0);
	platform_set_drvdata(raumfeld_audio_device,
                             &snd_soc_raumfeld);
	platform_device_add(raumfeld_audio_device);

Or is this not any longer correct?
