do you mean node 0x16 is the subwoofer ?
have you try changing this node to line out with Misc = NO_PRESENCE ?
both node 0x14 and node 0x16 have the front channels and
line out won't mute speaker
headphone can still automute speaker and line out
[ALC662_FIXUP_ASUS_MODE4] = {
.type = HDA_FIXUP_PINS,
.v.pins = (const struct hda_pintbl[]) {
{ 0x14, 0x99130110 }, /* speaker */
{ 0x16, 0x99130111 }, /* speaker */
{ 0x18, 0x01a19840 }, /* mic */
{ 0x19, 0x99a3094f }, /* int-mic */
{ 0x21, 0x0121441f }, /* HP */
{ }
},
.chained = true,
.chain_id = ALC662_FIXUP_SKU_IGNORE
