You may need to ask Takashi , David, PA developers and Media
controller developers how to handle this case

since it may need to set_pin_ctl to PIN_HP and PIN_OUT of 0x1b and
retasking of input jacks as output  whether PA or Media controller API
expect to change the name of the volume control and switch from
"Headphone" to "Front" by hda-reconfig

you can use hda-verb to set the pin default of 0x17 and use
hda-jack-sense-test retest the side jack

The red light is due to you turn "IEC958 Default PCM" on since this
switch copy the signal to digital out

If you don't use SPDIF, may need to turn off this switch to turn off
red light and save power for your notebook

Simple mixer control 'IEC958 Default PCM',0
  Capabilities: pswitch pswitch-joined penum
  Playback channels: Mono
  Mono: Playback [on]


To add the missing pin default of side jack 0x17

	ALC662_FIXUP_ASUS_MODE8,
+	ALC892_FIXUP_CLEVO_4ST_8CH,
};

static const struct alc_fixup alc662_fixups[] = {


+	[ALC892_FIXUP_CLEVO_4ST_8CH] = {
+		.type = ALC_FIXUP_PINS,
+		.v.pins = (const struct alc_pincfg[]) {
+/*
+  need to be same location as the other jack
+  may need to change the default association and sequence since
+  Lower Default Association values would be higher in priority for resources
+  such as processing nodes or Input and Output Converters.
+  A value of 0000b is reserved and should not be used
+*/
+			{ 0x17, 0x01011013 }, /* Side */
+			{ }
+		},
+	},


+	SND_PCI_QUIRK(0x1558, 0x5102, "Clevo P150HM", ALC892_FIXUP_CLEVO_4ST_8CH),
+	SND_PCI_QUIRK(0x1558, 0x7100, "Clevo P170HM", ALC892_FIXUP_CLEVO_4ST_8CH),

SImilar case are those notebooks  hda-emu/codecs/alc1200-msi-gx620
which has 1 hp(green), 1 line-in(blue), 1 ext-mic(pink) and 1 line
out(grey) at same location (ext rear)   for surround71 (and also 1
speakers, 1 int mic)

> get 1
1 Channel Mode:0
ITEM: 0:2ch, 1:4ch, 2:6ch, VAL: [2ch]

what is missing are
1) 8ch in "Channel Mode" ,
2) Side Playback Volume
3)Side Playback Switch

Study the logic to add 8ch and "side" in

1) alc_auto_fill_dac_nids()
2) alc_auto_fill_multi_ios() which add line-in and mic jack to multi_ios,


This mean that when switch to 6/8 channel mode, it will conflict with
automic detection since the pin cap alc892 's mic jack does not
support impedance sense and the driver does not know the plug is mic
or speaker by measuring the impedance

The driver have to disable automic detection when user switch "channel
mode" to 6ch/8ch as the user should still able to use the internal mic
when the external mic jack is retasked as output

you have to find out whether subwoofer is connected to 0x16 of your
p150hm since your mic jack (retasked as clfe) is connected to dac 0x4.
