First time posting on the Onion Community... Hello, hello.
The Omega2 has seemed very promising as a fast track to product development and I commend the efforts of the Team and Community.
I am also looking to get i2s audio functioning on an Onion Omega2. I am working on a product where we had been considering the LinkIt Smart 7688 as an embedded solution, but it suffers from a lack of support when it comes to running more modern OpenWRT with i2s functionality, similarly unsupported by the larger OpenWRT community.
I was hoping that the i2s functionality on the Onion Omega2 would make this a clear alternative to the LinkIt Smart 7688, however it seems that they both lack the attention to get the feature running.
All of this is to say that I just wanted to add my voice and product needs around a functioning embedded linux solution that has out of the box i2s audio support.
I've scraped together whatever information that I can to attempt to get i2s functioning by way of building my own custom firmware with ALSA enabled and DTS files altered only to result in:
A) a custom built firmware with almost functioning i2s (ALSA detects a "card") but no proper playback
B) a custom built firmware with no functioning i2s even though I seem to have all of the puzzle pieces in place
C) a custom built firmware that crashes on boot
I'm really not sure what's next to experiment with, but any input would be greatly appreciated on either a path towards a solution running i2s on the Omega2, or suggestions on an device alternative that is in the same price range but is committed to supporting i2s audio.
