I then thought that it was aimed at MB51 not MBP51: mecbuk 2009 # cat /sys/module/snd_hda_intel/parameters/model mb51,<NULL>,<NULL>,<NULL>,<NULL>,<NULL>,<NULL>,<NULL> The subsystem ID of my ALC889A codec is : 0x106b4000 The mb51 quirk is automatically applied to : + case 0x106b3f00: /* Macbook 5,1 */ + board_config = ALC885_MB5; + break; so it seems that the codecs differ. I actually made it work by changing VREF of Node[0x18] PIN from HIZ to any of 50,80 or 100. This fixed the sound, also enabling the surround slider which vastly improves the sound quality and loudness. But still there are problems with the headphone/internal speaker functioning. If you think that this will require another model quirk for patch_sigmatel, I really want to get involved on providing the necessary informations to you.
