	-----------
        /* set codec DAI configuration */
        ret = snd_soc_dai_set_fmt(codec_dai, SND_SOC_DAIFMT_I2S |
                                             SND_SOC_DAIFMT_CBM_CFM);
        if (ret < 0)
                return ret;

        /* set cpu DAI configuration */
        ret = snd_soc_dai_set_fmt(cpu_dai, SND_SOC_DAIFMT_CBM_CFM |
                                           SND_SOC_DAIFMT_NB_NF);
        if (ret < 0)
                return ret;

I'm also still trying.
