3.13-stable review patch. If anyone has any objections, please let me know.
------------------ From: Hui Wang <[email protected]> commit 493a52a9b6645f61954580c7d4bd52fa62110934 upstream. On some AIO (All In One) models with the codec alc668 (Vendor ID: 0x10ec0668) on it, when we plug a headphone into the jack, the system will switch the output to headphone and set the speaker to automute as well as change the speaker Pin-ctls from 0x40 to 0x00, this will bring loud noise to the headphone. I tried to disable the corresponding EAPD, but it did not help to eliminate the noise. According to Takashi's suggestion, we use amp operation to replace the pinctl modification for the automute, this really eliminate the noise.
