Chord Mojo is working nicely with the Pi 2 and 0.3 beta. 16/44.1, 24/192 and 24/96 all play without issue.
The bit rate indicator is also showing the change in bit rate each time so the Mojo is detecting the bit rate changes as each track starts.
There is a 1 second delay in playback if you change bit rates. I believe this is known issue with the Mojo.
