[alsa-devel] How to specify data format if playback/capture were different ?

Hi Mark, and ALSA ML

Now, I'm creating ak4554 AD/DA. My question is about data format.

If my understand is correct, we can specify cpu/codec deivce data format by using

snd_soc_dai_set_fmt(dai, SND_SOC_DAIFMT_xxx);

But, ak4554 case, data formats are playback : SND_SOC_DAIFMT_RIGHT_J capture : SND_SOC_DAIFMT_LEFT_J and, it can't exchange this data format.

CPU driver should set these information for ak4554 when playback/capture.

Then, how to specify these data format on ALSA SoC ?
