Well, that does sound easier than rewriting the whole thing. I'll give it a go at instantiating multiple codecs.
Would this be 'substreams' or is that something else?
Sorry to be ignorant, but I'm a newbie to kernel development (I've successfully brought up GPIOs and the I2C mux on my board, so I at least have some simple stuff under my belt).
Thanks again, -Caleb

Yes.
This seems like it won't work because I'd end up with multipleuser-space 'cards', yet I want the card to appear as a single 16-channel sound card. Also, when you start one PCM interface for one codec, they
No, you shouldn't. You'll end up with a single card.
would all start automatically, which I imagine the linux system wouldn't get. Also, the PCM interface needs to be configured differently for each codec (the TDM offset must be 0, 16, 32, 48, etc. bits).
The TDM stuff should be configured with the existing TDM API (you may need to implement this in the CODEC driver).
