TLV320AIC3262: Mixer IN2L/R + I2S1 + I2S2 to I2S3

Part Number: TLV320AIC3262

Hi Expert,

I used the below PFW to run AIC3262, but I can't hear I2S2. Should I add other command for it? Thanks!

PS. IN2L/R and I2S1 are OK!

    Hi, Jerry,

    It seems you are using I2S3 as the digital output interface (I2S_Out3), not I2S2. In general when either I2S2 or I2S3 are used in a process flow, the system settings code is updated to enable the corresponding interface.

    Hi Diego,
    Yes, I am using I2S3 and analog output. The input is from IN2, I2S1 and I2S2. I think the PPS can auto setting it, but I can hear IN2 and I2S1 data from HP out only. Any idea for I2S2 setting? Thanks!

    Hi, Jerry,

    Thanks for the feedback. The interfaces should be programmed automatically, but just to make sure, can you please send me the .cfg file generated in your application for review?. Can you please also confirm if I2S3 is working well?.  I assume you are using an EVM, if so, can you please share the connections you are doing to the interface I2S2?.

    Best Regards,
