    ALSA: hda - Workaround for silent output on VAIO Z with ALC889 · e427c237
    Takashi Iwai authored
    On recent kernels, Realtek codec parser tries to optimize the routing
    aggressively and take the headphone output as primary at first.  This
    caused a regression on VAIO Z with ALC889, the silent output from the
    speaker.
    
    The problem seems that the speaker pin must be connected to the first
    DAC (0x02) on this machine by some reason although the codec itself
    advertises the flexible routing with any DACs.
    
    This patch adds a fix-up for choosing the speaker pin as the primary
    so that the right DAC is assigned on this device.
