Hui Wang, Yes, this solves the noise issue. Both the modprobe method from Lenovo forum and the command you provided work perfectly. Thank you, and thank you James!
I still have quiet sound initially. And, now that I compared it to the kernel without the 0x12 line, it seems that the sound is quieter also after replugging the headphones (which must be dome while sound is playing). It's about 20dB lower before replugging and about 10dB lower after, and perhaps less bassy, though I may be imagining things here. I'm testing it with http://www.vygo.net/hda/11-Ultimatum.ogg which has strong bass indeed. But I understand that you can reproduce it, so I trust in you :) Many thanks for solving the noise issue, and happy new year!
