    ALSA: hda/realtek - Fix overridden device-specific initialization · 89781d08

    The recent change to shuffle the codec initialization procedure for
    Realtek via commit 607ca3bd ("ALSA: hda/realtek - EAPD turn on
    later") caused the silent output on some machines.  This change was
    supposed to be safe, but it isn't actually; some devices have quirk
    setups to override the EAPD via COEF or BTL in the additional verb
    table, which is applied at the beginning of snd_hda_gen_init().  And
    this EAPD setup is again overridden in alc_auto_init_amp().
    For recovering from the regression, tell snd_hda_gen_init() not to
    apply the verbs there by a new flag, then apply the verbs in
