Re: [alsa-devel] hda-intel front headphone (8086:27d8 1043:83bc)
My knowledge of audio/alsa programming is really poor, but if someone suggest a patch I can setup the thing and do some debug.
Try Takashi 's daily snapshot tarball
you should able to get "Headphone Playback Volume" after this patch "ALSA: hda - Code consolidation for ALC88x and ALC662 auto-parsers"
using hda-emu and it seem the driver support 6 channels even when the pink and blue jacks are not retasked

Hi Raymond, thanks for your support
built and installed the daily snapshot, the driver tarball only, now the mixer applications show adjustable headphone volume level, but still hear nothing. Should upgrade alsa lib or something else too?
Just a note, in the bios there's some related option: Audio Controller: [Azalia]/Disable all Front panel Support type: AC97/[HD Audio]
I checkd both AC97 and HD with the new alsa-driver with the same result.

you may need to provide output of alsa-info.sh
configure --with-debug=verbose

Do your computer chassis have a HD Front Audio Panel ?

You can also physically check the audio cable of the front panel audio solution. If there is a cable connected to Pin 4, you have an HD Audio module; if there is no cable to Pin 4, you have an AC97 module.
The difference between AC97 and HD Audio "Front panel Support type:" in BIOS setup is Misc[11:8] of Configuration Default is a bit field used to indicate other information about the jack. If bit 0 is set, it indicates that the jack has no presence detect capability, so even if a Pin Complex indicates that the codec hardware supports the presence detect functionality on the jack, the external circuitry is not capable of supporting the functionality
you can use hda-jack-sense-test

Sorry I was missing all this stuff, for some unknown reason I was also sure everything working with windows but have checked today and it isn't
The chassis seem to support HD Audio http://www.coolermaster.com/product.php?product_id=5239

You got it, guess something wrong here, I'll double check the cable and connections soon in few days then back here and let you know

Currently it work with the rear panel only
Pin 0x14 (Green Line Out): present = Yes Pin 0x18 (Pink Mic): present = No Pin 0x1a (Blue Line In): present = No
Thanks!
