Other Parts Discussed in Thread: TLV320AIC3111

Hi all,

I am using TLV320AIC3111 codec. and able to control the codec through I2C but not getting data on I2S lines. I am using I2S0 from my hardware,

can anyone suggest me how to configure I2S0 from software side, or how can we conclude which I2S is using from data transfer from software side?

    Hi Nikhil,

    Could you please be more specific about the I2S configuration desired?, you can take a look to this document, it explains how to configure Audio Serial Interface with audio codecs. You can also use AIC3111 GUI to configure the signal routing as you want, save it to a I2C script and then load it into your system.

    i made the setting alsa_amixer correct and play the command

    alsa_aplay -c 0 <path><audio_file_name>
