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.
