hanni76 Posted June 7, 2017 Share 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 Link to comment Share on other sites More sharing options...

hanni76 Posted June 23, 2017 Author Share 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.
