    ALSA: hda - Keep EAPD turned on for old Conexant chips · 254f2968
    Takashi Iwai authored
    In the old Conexant chips (5045, 5047, 5051 and 5066), a single EAPD
    may handle both headphone and speaker outputs while it's assigned only
    to one of them.  Turning off dynamically leads to the unexpected silent
    output in such a configuration with the auto-mute function.
    Since it's difficult to know how the EAPD is handled in the actual h/w
    implementation, better to keep EAPD on while running for such codecs.
