hanni76 Posted June 7, 2017 Posted June 7, 2017 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

hanni76 Posted June 23, 2017 Author Posted June 23, 2017 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
