Neil,I think I can help. I worked on a custom prototype board and set up my own TLV320 with an Octavo RED board in predevelopment in the device tree and is working fine. Some things you absolutely need to know before changing things in the cape dts file.-What I2C bus and pinmux are you using.-What MCASP bus are you using in pinmux? Definitely need 2 of the 4 RX pins. - You need to learn how to set up your asound.conf file. This has so many possibilities based on how you want to sample the audio. -If using a cape and making changes, use install.sh or it won't work.-The better option is to learn how to create your own device tree and put it as an Overlay in the uEnv.txt file. If the actual cape hasn't changed at all (pins). Then I'll show you how to just make a device tree of that cape overlay. I'll provide more details tomorrow. Regards, Ray

This is the dts file associated with cape board and has worked fine on the older 3.x kernels: BB-BONE-AUDI-01.dts It doesn't seem to be installed/supported as part of the latest /lib/firmware directory.
