TLV320AIC3101 Codec, integrating with Imx8mp Failed to derive required Rx rate: 1411200

[MJD]

Hi @nxp
we are trying to integrate TLV320AIC3101 codec and we are able to listen only over 48000 sample rate audios but when we play 44100 sample rate or any other we are facing with the bellow error.

30c30000.sai-tlv320aic3x-hifi: ASoC: error at __soc_pcm_hw_params on 30c30000.sai-tlv320aic3x-hifi: -22

Hello,

You are getting that error because PLL/prescaler cannot provide requested frequency to play audio at 44.1 KHz sample rate.

If you need to reproduce at that sample rate, maybe you should use an external crystal to provide necessary clock frequency or modify clock driver to provide necessary frequency.

Best regards.

Hi @JorgeCas 

Thank you for your response,

Can you please provide, any resolved configuration with this issue as a reference.

And providing external clock is not fissable with our custom board.
