AM335x record wav file then play have noise

Hi, everyone

    My plafrom is AM335X, SDK6.0, the audio IC is tlv320aic3106

    The SDK6.0 audio format is DSP mode, the define:

    #define AUDIO_FORMAT (SND_SOC_DAIFMT_DSP_B | SND_SOC_DAIFMT_CBM_CFM |SND_SOC_DAIFMT_IB_NF)

    My SPEC nedd is I2S mode and FRM master, so I modify code is:

   #define AUDIO_FORMAT (SND_SOC_DAIFMT_I2S  | SND_SOC_DAIFMT_CBM_CFM | SND_SOC_DAIFMT_IB_IF)

   Now, play audio file is OK, but record a wav file, the play this file,  the noise is very big

   So, I want to know that if I2S mode, the audio format define?
