path_has_mixer() does not imply shared volume

get_amp_nid_( path->ctls[NID_PATH_VOL_CTL] )  of two paths are same

if you just want Front+Headphone playback volume

As the original config only support stereo, pcm playback volume control
line out volume , headphone and speaker using different DAC 0x02 and 0x03

Try specify

spec->gen.indep_hp = 1;

before callin the auto parser in patch_alc662

Device: name="ALC662 rev3 Alt Analog", type="Audio", device=2

should appear in node 0x03 which has headphone playback volume
