I am posting from a live install of trusty-desktop-amd64.iso and am happy to say that A2DP audio works again! The dmesg firmware error still exists though. I noticed too that although sound works on my BT headphones, the mic input does not get picked up by the ubuntu sound utility. Perhaps it should be relegated to a seperate bug report.
