Any pointers to solve the issue.

Got the solution from another mailing list.
Tested and found it to be working.

For motherboard with 3 audio jacks at rear panel and 10 channels HDA codec

you need to retask headphone at front panel as side line out

the easy way is to use hdajackretask (advanced override) or early patching to retask

if green line out at rear panel has sequence 1 in pin default.

1) blue line jack as Line Out with sequence 2
2) pink mic jack as Line Out with sequence 3
3) front panel headphone to Line out with sequence 4

the three retasked line out should have same default association as the green line out

in theory, it is possible to add the retask of headphone to line out into the existing channel mode (8ch) when the codec has extra DAC and volume control using multi_Ios pin butt need to hack the jack detection control, disable auto mute and independent headphone when the headphone is retasked
