Hello guys

 

I am looking for any help or hint on how to start the work stated in the title:  Porting Audioinjector Pi SoundCard overlay from Raspbian to Armbian.

I would like to use the card on OrangePi platform based on because H3 SoC has all required hardware: I2C, SPI, I2S(?).

The code I found is in Raspbian github repository https://github.com/raspberrypi/linux/tree/3f53e7886737a975e3fe76bc8ae6cc78f33c8cf8/sound/soc/bcm.

As far as I see, the sound card driver is based on WM8731 codec and it is using on BCM SoC I2S interface..  

Can I use the similar I2S interface on Sunxi SoC? Does current mainline linux allow me to do this port at all? What is missing ?

Can you help me understand at least required steps to get this work done ? What should I start from ?

 

Thank you

No I2S support for H3 yet

Yes, seems like someone is working on it..

Hello,

seems like someone has integrated I2S for H3 patch into this fork: https://github.com/orangepi-h3-linus/orangepi_h3_linus/

I am going to try it and let you know if it works.

 

Thanks
