    D. Hartl
    You cannot connect the I2S DIN and DOUT signals together and achieve independent operation of the ADC and the DAC. One is used to transfer digital audio data from the uC to the codec and the other one is used to transfer digital audio data from the codec to the uC. Please check, if you are mixing up...

    Hello, We use the AIC3104 together with a microphone connected to MIC1LP/LINE1LP and MIC1LM/LINE1LM. Our intention was to generate the sample frequency using BCLK (4.096 MHz) instead of using MCLK (12 MHz). It looked like it was OK and to check that BCLK was really used we disconnected MCLK...

    hi MS so the decimation filter must be used, chosing among A filter, B filter and C filter. " The TLV320AIC3204 offers 3 different types of decimation filters. The integrated digital decimation filter removes high-frequency content and down samples the audio data from an initial sampling rate...

    Hi, We have the problem with our codec tlv320aic3104...I'm already using L1/R1... I think the problem comes from DAC when it power up. Is there any reserved register we can configure to enable auto mute DAC like aic32XX ? Thank you
