GPIO: io=3, o=0, i=0, unsolicited=1, wake=0
- IO[0]: enable=0, dir=0, wake=0, sticky=0, data=1, unsol=0
+ IO[0]: enable=0, dir=0, wake=0, sticky=0, data=0, unsol=0
    IO[1]: enable=1, dir=0, wake=0, sticky=0, data=0, unsol=0
    IO[2]: enable=0, dir=0, wake=0, sticky=0, data=0, unsol=0

Seem gpio are different

Those  unsolicited event of mic jacks were not enabled

You need to use hda-jack-sense-test
