This approach currently works well on the twl4030. However, you may want to consider using SND_SOC_DAPM_AIF_IN() for your input paths here. e.g.

AIF_IN -> MIXER -> DAC -> rest of codec

I was also thinking to restructure the TWL4030 codec to have the AIF_IN and AIF_OUT widgets. We do have digital routing selection before the DACs (and mixers), which as it is now not in the codec driver, but it would be nice to have them at some point. I have them in a custom board file (as simple kcontrols), and as I recall I have sent a sample patch for beagle to add those in the machine driver. Or I have not sent, I'm not sure..
