TLV320AIC3254: setting

Part Number: TLV320AIC3254

Hi team,

My customer is using AIC3254 in an infotainment project, the tuner is input from IN2_R/L, and the USB is input from I2S.

And customer found that, when the whole system power on, if I turn on tuner firstly, there is no sound. I have to turn on USB firstly and then turn it off, and then turn on tuner, only with this sequence the tuner will work well.

And we have tried to set the I2S clock as master mode during tuner is on, but nothing change.

So I wondering if you have met similar issue and any solution towards it?

    Hi, Fery,

    Can you please share more details about the overall configuration of the device, tuner and USB?. It seems that there is some dependency with the USB module to start the normal operation mode. Do you have details about the clock configuration of the codec [sampling rate, master clock source/frequency, etc.]?

    Best Regards,
