Dear Sir,

I using aic3104 EVM with GUI, select configuration "ON Board MIC ...", it can record success.

I change using aic3109 EVM, also select GUI "aic3104", and the same select configuration "ON Board MIC ...", it can not record.

What setting I need to set for record by aic3109 EVM?

Thanks,  Ian.

    Ian,

    The AIC3104 uses MIC3L/R for the Microphone. But The AIC3109-Q1EVM uses LINE/MIC1L.

    when you run the on Board mic preset, the script below will show in the command line interface tab:
    i i2cfast
    w 30 11 0F
    w 30 12 F0
    w 30 16 7C
    w 30 13 7C
    w 30 0F 00
    w 30 10 00
    w 30 19 80


    Just change the fourth command to w 30 13 04 then click "execute command buffer" and you should get the mic signal.

    best regards,
