Hui Wang, Without the 0x12 line (but with the rest of your patch) there is no noise.
Likewise, with your patch (standard kernel), running hda-verb or loading the module with the equivalent options also stops the noise. Additionally, with your full patch the sound is 10dB lower (or 20dB lower before replugging the headphones) than without the 0x12 line.
