But when wm8350 in i2s mode, it take SND_SOC_DAIFMT_NB_NF as LRCLK is 0 for frame start.
I2S frame start is the LRC going high (from low) to indicate left channel PCM data is available after the next bit clock.
Correction. I've just noticed my datasheet is wrong here.
I2S LRC Left = low, right = high.
So frame start is LRC going low from high.
