[alsa-devel] ATMEL sam9g25 SSC in I2S slave mode on linux 4.1.1 play only right channel

I'm working on my based sam9g25 design. To have SPDIF output I used cs4265 codec instead of wm8731 as sem9g25 reference design. Now I'm working on porting of cs4265 codec driver. It work for play only right channel, left channel is mute and not supplied by SSC. SSC is configured as I2S slave : SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_CBM_CFM

Do you know this behaviour ? There is a patch for fix it ?

Thank you in advance.
