so here you keep the DP but remove HDMI

but here you remove both? I guess you forgot to remove DP earlier?

What about the other routing table?

static const struct snd_soc_dapm_widget kabylake_5663_widgets[] = {
	SND_SOC_DAPM_HP("Headphone Jack", NULL),
	SND_SOC_DAPM_MIC("Headset Mic", NULL),
	SND_SOC_DAPM_SPK("DP", NULL),
	SND_SOC_DAPM_SPK("HDMI", NULL),

static const struct snd_soc_dapm_route kabylake_5663_map[] = {
	{ "Headphone Jack", NULL, "Platform Clock" },
	{ "Headphone Jack", NULL, "HPOL" },
	{ "Headphone Jack", NULL, "HPOR" },

	/* other jacks */
	{ "Headset Mic", NULL, "Platform Clock" },
	{ "IN1P", NULL, "Headset Mic" },
	{ "IN1N", NULL, "Headset Mic" },

	{ "HDMI", NULL, "hif5 Output" },
	{ "DP", NULL, "hif6 Output" },

it'd be good to be consistent, wouldn't it?
