I started MS Windows and without externals speakers plugged in I could

test

5.1 configuration and it seemed that sound was coming from different

directions.

What I managed to determine: I've got 3 stacks: 1 ST: Headphone, Line-out (FL and FR), SPDIF 2 ST: Microphone, Line-out (CLFE) 3 ST: Line-in, Line-out (RL and RR)

I've got 5 responsive output pins PIN 0x14: Internal FL FR PIN 0x15: External FL FR PIN 0x17: Internal LFE PIN 0x18: External CLFE PIN 0x1a: External RL RR

How can we make it work with these information?

seem chnmap type _FIXED , _VAR and _PAIRED does not fit when LFE and FC can be swapped for internal speaker and external speaker

How do the driver implement channel map when codec has swap center/lfe switch ?

Do chnmap contain both {FL FR RL RR FC LFE} and {FL FR RL RR LFE FC} ?
