Hi,
There is a fourth driver file that the Linux documentation for the device mentions, "tlv320aic31xx-micbias.h". I will attach it here, it just defines the bias values which may help. You could even copy the definitions and put them at the top of the…

Hello TI,
Is there any way or register (like vendor id / product id register most of the chips have) to identify the chip connected on board at run time from…
The driver didn't supported my "MCLK" so routing failed. My MCLK 12.8MHz was also not supported by the aic31x clock divs. I also integrated all fixed from upstream linux kernel master. Audio Output is now working, microphone currently not…
Part Number: TLV320AIC3100 Hi,
We are using TLV320AIC3100IRHBR as audio codec interface for our Embedded Linux Platform developed using Yocto Project (Kernel Version used is 4.14.98).
To enable the driver support, "Texas Instruments TLV320AIC31xx CODECs…
Hi Mir,
I am a strong believer in RTFM also! I was looking at the simple-audio and tlv320aic31xx driver documentation. Lacking experience in device tree, can't figure out the proper syntax or how the device driver interacts with the device tree overlay…
Hi,
I recommend you to use the same dai structure as the Linux driver； https://www.ti.com/tool/TLV320AIC31XX-DRIVERS
You can add a default setting array after reset.

Hi Mir,
The issue we encountered was that we couldn’t output a different sample rate than the input simultaneously, and it’s related to the Linux "tlv320aic31xx" driver. I didn’t try updating the codec via I2C because, AFAIK, ALSA manages the audio control…
Part Number: TLV320AIC3100 Tool/software: Hello.
We are trying to implement an audio device with TLV320AIC3100 codec, our device has a MPU STM32MP135D with Linux 5.15.67.
You can see the schematic in the following link.

Hi Bin,
I did some tests with kernel version 6.1.112 instead of 6.1.119 because that was the version I tested last time and it was ready to use on our board. I am sorry to say that the GPIO wake up does not work and it does not seem to be a problem with…
