Hello Ffanci,

Haven't touched my RPi1 in a while but it ran quite well, slightly
better than with an USB audio interface:

I mostly used the Wolfson card with -r48000 -p128 -n2.

Is the Cirrus Logic now supported on rpi2?

It's fully supported now:

Did some measurements recently with jack_iodelay and the Cirrus Logic
interface and output/input latency is really low.
