Frank, Maybe it would be better to ask for your help in what I am trying to do, then...
What I want to experiment with is Jack2, specifically Jack2-net played through the i2s card. The kernel, at least on the PiB+, does not support the i2s as mmap is not enabled. There is a guy that has patched the kernel so that mmap will work with the i2s driver. I tried it with my piB+ and got no output, though it appeared to be 'connected' via jack. I want to try this with the B2 as that is what he was using. The link where I found the info is here (his diff to the kernel is there as well):

I'd like to have jack2 working so I can test out a few things, but it does not appear that this is in the kernel. will have to try it again after I reinstall the Pi2 RuneOS software... I messed it up somehow.
