Hi to All,

 

I am new in this IMX8MQuad processor.

We have an EVK for this IMX8MQuad.

If we check audio part, audio codec is not working.

But when we tried with hdmi audio its working fine.

we checked the following commads to verify audio cards present or not.

# cat /prov/asound/cards then imxhdmiaudio only available.

while booting ALSA device list also shows only #0 imx-audio-hdmi.

 

What is the issue how to solve this?

 

In our actual board we are using TLV320DAC3203 how to include this audio codec into our project and how to build after these changes.Which device tree need to changes?

Thanks in advance

 

Regards,

prathap
