Hello all,

 

I'm new to Linux world. I'm working on iMX6Q and I need to add a new sound card and recognized from alsamixer.

I spent days on internet looking for examples and tutorials but at the moment alsa never see my sound card.

This is one of the tutorials I followed Linux source code: Documentation/devicetree/bindings/sound/simple-card.txt (v4.5) - Bootlin 

What I've done?

- Activated support for generic sound board on menuconfig

- Added new "sound" node in device tree file with minimal properties/subnotes

 

By the way, the project is a Yocto project.

 

Is this enough for let alsa see the sound card? or something is missing?

 

Thanks to all for the help.
