@Raymond
Checked this. reverted ef4da45828603df57e5e21b8aa21a66ce309f79b and changed read_widget_caps to:
static int read_widget_caps(struct hda_codec *codec, hda_nid_t fg_node)
{
	int i;
	hda_nid_t nid;

	codec->num_nodes = snd_hda_get_sub_nodes(codec, fg_node,
						 &codec->start_nid);
	if (codec->vendor_id == 0x11068446)
		codec->num_nodes = 55;
	codec->wcaps = kmalloc(codec->num_nodes * 4, GFP_KERNEL);
	if (!codec->wcaps)
		return -ENOMEM;
	nid = codec->start_nid;
	for (i = 0; i < codec->num_nodes; i++, nid++)
		codec->wcaps[i] = snd_hda_param_read(codec, nid,
						     AC_PAR_AUDIO_WIDGET_CAP);
	return 0;
}

The issue remains. I used 3.15.6 sources.
