TLV320DAC3100 audio codec with IMX93 SoM

[LAAZIBI]

I am trying to test the TLV320DAC3100EVM-U kit with IMX93QS93 Linux board. I am able to detect it know as you can see here: 

root@qs93-5210:~# aplay -l

- But when I tried to aplay sine wave I got the following errors:

I am struggling to make this work, could anyone help me out with this?

And playing sine wave seems to be working with (480kHz, 441KHz), as there are no error in output, But not the case for (48kHz).

 What could be the problem here and the clock frequency is set to 12,288MHz (multiple of 48kHz) ?

Thank you for your support. 

I am currently using the official Linux kernel driver for the TLV320AIC31xx audio codec, as provided by the kernel maintainers. It supposed to work fine for my codec, but I will try to use the third party Linux driver and see. 

- I double checked the CODEC voltage and seem to be correct. 
- The clocks should be configured as expected but I might be wrong in something.  
- No, I am not seeing any thing related to audio mapping --> ok.

Hello,

Hope you are doing well; I will be working in your support case.

The TLV320DAC3100 audio CODEC is not supported by default on our BSP. To use this CODEC to your system, you need to add a third-party driver provided by Texas Instruments and configure your device tree.

Unfortunately, there is not a guide to port this specific CODEC to the BSP. The references we have are the i.MX porting guide and EVK device tree (WM8962).

I see that you are using the simple audio card provided by Linux as the Machine driver. I don't recommend customers to do this and try with TI driver.

Here some debugging recommendations:

• Check that CODEC voltages are according to manufacturer specifications.
• Check that clocks are configured as expected.
• When Linux starts, can you see the prompt of audio mapping-->ok?

Best regards.
