Please consider changing patch title to document the change you did so: "ASoC: Intel: use MCLK instead of BLCK as the sysclock" describes this patch rather than current one.. > > Signed-off-by: Harsha Priya <harshapriya.n@intel.com> > --- > sound/soc/intel/boards/kbl_rt5663_rt5514_max98927.c | 13 ++----------- > 1 file changed, 2 insertions(+), 11 deletions(-) > > diff --git a/sound/soc/intel/boards/kbl_rt5663_rt5514_max98927.c b/sound/soc/intel/boards/kbl_rt5663_rt5514_max98927.c > index cfde894..cfd89ca 100644 > --- a/sound/soc/intel/boards/kbl_rt5663_rt5514_max98927.c > +++ b/sound/soc/intel/boards/kbl_rt5663_rt5514_max98927.c > @@ -351,19 +351,10 @@ static int kabylake_ssp0_hw_params(struct snd_pcm_substream *substream, > return ret; > } > > - ret = snd_soc_dai_set_pll(codec_dai, 0, > - RT5514_PLL1_S_BCLK, RT5514_AIF1_BCLK_FREQ, > - RT5514_AIF1_SYSCLK_FREQ); > - if (ret < 0) { > - dev_err(rtd->dev, "set bclk err: %d\n", ret); > - return ret; > - } > - > ret = snd_soc_dai_set_sysclk(codec_dai, > - RT5514_SCLK_S_PLL1, RT5514_AIF1_SYSCLK_FREQ, > - SND_SOC_CLOCK_IN); > + RT5514_SCLK_S_MCLK, 24576000, SND_SOC_CLOCK_IN); > if (ret < 0) { > - dev_err(rtd->dev, "set sclk err: %d\n", ret); > + dev_err(rtd->dev, "set sysclk err: %d\n", ret); > return ret; > } > } > -- > 1.9.1 >

This patch fixes the pop noise in dmic recording using rt5514 on kabylake platform. This patch enables the rt5514 to use MCLK instead of BLCK as the sysclock which fixes the pop noise.
