    ALSA: hda - Fix headphone pin config for Lifebook T731 · cc7016ab
    Takashi Iwai 提交于
    Some BIOS version of Fujitsu Lifebook T731 seems to set up the
    headphone pin (0x21) without the assoc number 0x0f while it's set only
    to the output on the docking port (0x1a).  With the recent commit
    [03ad6a8c: ALSA: hda - Fix "PCM" name being used on one DAC when
     there are two DACs], this resulted in the weird mixer element
    mapping where the headphone on the laptop is assigned as a shared
    volume with the speaker and the docking port is assigned as an
    individual headphone.
    
    This patch improves the situation by correcting the headphone pin
    config to the more appropriate value.
