[ALSA] hda-codec - Fix Master volume on HP dv8000
HP dv8000 laptop has a problem with Master volume. It's due to the connection of the widget 0x13. When it's connected from the analog amp mixer (0x19), it works as expected mysteriously (ALSA bug#3775): https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3775 Signed-off-by: Takashi Iwai <tiwai@suse.de>
