Obviously your front-panel doesn't suit with the HD-audio, and BIOS still doesn't set the right pin defaults. That is, it was a bug of the driver that made your device working :) Now, the driver does the right thing. A possible fix is to add quirks to override the wrong BIOS setup. Please give alsa-info.sh outputs with and without the commit to figure out the real pin configuration.
