[alsa-devel] [PATCH] ALSA: hda - Add one more node in the EAPD supporting candidate list

[Hui Wang]

We have a HP machine which use the codec node 0x17 connecting the
internal speaker, and from the node capability, we saw the EAPD,
if we don't set the EAPD on for this node, the internal speaker
can't output any sound.
