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 outputs with and without the commit to figure
out the real pin configuration.
