I have this bug and managed to fix it temporarily on vpceb1c5e:
using HDA analyser I set NODE 0x19 Widget Control VREF from 50 to HIZ
or GRD (either seems to work) -- this enables PLAYBACK only, jack sense
between loudspeaker and headphone jack does work, I will try and dig up
what enables recording:
below diff for PLAYBACK
