Could you try a more recent driver version from ftp://ftp.suse.com/pub/projects/alsa/snapshot/driver ? There have been a lot of changes since 14rc3 was released, including some Mac specific changes, although it may not be specific to your system. Also, if you could, rebuild 14rc2 with "./configure --with-cards=hda-intel --with-debug=detect", reload them and test that headphones work again, and send me the output from "dmesg|fgrep ALSA", so I can hopefully determine which Node the headphones are on. Additionally, if you could run http://bulletproof.servebeer.com/alsa/scripts/alsa-info.sh on both 14rc2 and the latest driver for comparison, that would really help.
