master output volume doesn't affect actual volume

Bug Description

The pulseaudio volume control (master "output volume" in sound settings, or the volume applet/keys) does not seem to affect the catual playback volume of my headphone output. The application-specific volume control in the sound settings does change the volume as expected.

As far as I can tell, the actual output volume is 100% for any volume setting except "mute", which works.

The motherboard's rear audio out gets its volume changed as expected.

This was fine before I upgraded from oneric to precise.

Same problem. No fix seems to help link the Master output to my Headphones or PCM Can control via volume control app, but my volume wheel, which controls the Master volume, does nothing for my headphone output.

use 6stack or 6stack-dig if you want vmaster include headphone

In /etc/modprobe.d/alsa-base.conf

options snd-hda-intel model=6stack-dig

ad1988 and x1989 is a HDA codec with 10 channels DAC which support 7.1 + 2

The auto model allow you to play stereo to front panel headphone while playing 7.1 to rear panel jacks so the vmaster does not control the headphone volume

Raymond's fix did not work for me. What worked was commenting the sections in /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf and /usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf:
    #[Element Master]
    #switch = mute
    #volume = merge
    #override-map.1 = all
    #override-map.2 = all-left,all-right

does ad1989b need a separte hdmi device 3 instead of sharing device2 with spdif ?
(hdmi use 0x0b and spdif use0x02, hp use 0x03 and front use 0x04)

may be pulseaudio should not merge/use the virtual master by differientate the virtual master volume/switch control of snd-hda-intel driver from the master volume/switch of ac97 codec (e.g. mono control vs stereo control)

Thanks for the fix Jim. Works quite well.

I have a Intel Corporation 82801JI (ICH10 Family) HD Audio Controller for the record, and have been experiencing this since Precise. On Quantal now.

does it help if spec->vmaster_nid is changed from DAC1 to DAC0 ?

         spec->loopback.amplist = ad1988_loopbacks;
- spec->vmaster_nid = 0x04;
+ spec->vmaster_nid = 0x03;

        codec-> = 1;
        codec->no_sticky_stream = 1;
