you can try hda_jack_sense_test.py to measure the impedance of the rear
panel jacks

https://bugzilla.kernel.org/attachment.cgi?id=118731

this require the python and hda codec parser of hda-analyer

the BIOS of those motherboard which use IDT codec seem use
[Jack] Speaker at ext Rear for those line out jacks at rear panel

Node 0x0d [Pin Complex] wcaps 0x400181: Stereo
  Control: name="Speaker Front Jack", index=0, device=0
  Pincap 0x0000173f: IN OUT HP Detect Trigger ImpSense
    Vref caps: HIZ 50 GRD 80
  Pin Default 0x01114010: [Jack] Speaker at Ext Rear
    Conn = 1/8, Color = Green
    DefAssociation = 0x1, Sequence = 0x0


is it possible for the auto parser to put them into cfg->lineout when
device is speaker but the  connection is [Jack] and location is Ext Rear ?

the driver will not create those "line in jack mode" and "mic jack mode"
controls when it is desktop instead of notebook
