Looks like I missed that one.

The components now match on the dev_name().id (unless id == -1, then it
is dropped). Codec DAI is matched on codec DAI name.

e.g should be :-

+	.cpu_dai_name	= "au1xpsc-dai.0",
+	.codec_dai_name	= "wm8731-hifi",
+	.platform_name	= "au1xpsc-pcm-audio"
+	.codec_name	= "wm8731-codec.0-0026",

Can you give this a try. 

Thanks

Liam
