Other Parts Discussed in Thread: TLV320AIC3120
We are using TLV320AIC3120EVM-U connected to SDTM32MP135-DK.
Only the speaker is connected to LV320AIC3120EVM-U, no microphone is used.
The connections are below:
We have the following error:
The sound card does not find the MCLK1 and the clock are not enabled.
The device tree is below:

To create the device tree we use as reference the page: SAI device tree configuration - stm32mpu, "3.3.1 Setting SAI as a master clock provide"
How can we solve this problem? Do you suggest to change the device tree or the HW connections?
Regards
