Do you mean no optical spdif ?

> 1 x mic(line in)

Switching Mic Jack to line in can be performed by mic Jack mode switch
using hint add_jack_modes=true

You can use hda-verb GET_PIN_SENSE to test all the pin complex nodes which
pincap support DETECT

Did you use apply button(dyanmic reconfiguartion) or installment boot
override (early patching) ?

Pin Default 0x90170110: [Fixed] Speaker at Int N/A
    Conn = Analog, Color = Unknown
    DefAssociation = 0x1, Sequence = 0x0
    Misc = NO_PRESENCE

The rear speaker need  same default association but  sequence number higher
than that of the front speaker

The external subwoofer may use [jack] speaker with same default association
and higher sequence number if it can be detected

The driver won't use all of them for multi channel if you retasked it as
line out
