Some more follow up. If I disable (via capemgr) loading of BB-BONE-LCD4-01 with LCD connected then audio works - running dmesg after trying to run aplay with and without BB-BONE-LCD4-01 loaded shows two different results.

Running same test on 3.8.13-bone50 shows no such error. Note specifically error message regarding pinctrl-single 44e10800.pinmux with LCD4 loaded. Is this a red herring or indication of conflict?
