So... As for now i2s functionality is only available in theory, but can't be yet utilized practically? Did I understand correctly? Is there any chance this situation will change in the nearest future, or should I rather stick with Raspberry Pi when designing audio-oriented devices?

I am new member of Onion Omega Community, but until that point I was using several Linux boards in various projects (mainly Raspberry Pi). I never used anything OpenWRT based however.

I am interested in connecting I2S audio codec to the board. I prefer designing my own mainboards consisting needed peripherals, instead of stacking prefabricated modules.

Is there any popular chip with guaranteed compatibility with the Omega 2? With RasPi I was using wm8731, but they are much harder to get today. I mean something not needing complicated configuration and/or compiling own drivers.
