I just picked up an LG 29UC97 21:9 LCD, and my 5,1 (not flashed) does not detect display audio at all in OSX. It does the same over displayport and HDMI. My previous NEC monitor worked fine with displayport audio, and the LG seems to work fine in Bootcamp. Clearing PRAM and repairing permissions has not helped. Any suggestions?
I've also tested the monitor with my 2012 15" rMBP and it seems to work, though the system permanently switches on the nVidia chip when attached. My 2012 15" cMBP won't talk to the screen at all, but it's running 10.11 beta which could be the issue there.
