Thanks, analog playback device appear after specify model=intel-mac-v3

Audio still work with opensuse 12.1 Live CD

speaker-test hang and no sound with opensuse 12.2 Live CD

Only headphone playback volume and master playback volume of the emulated
STAC9221 affect the volume in 11.4 and 12.1 , the speaker playback have no
effect

And the emulated codec alway report headphone jack present

seem change in hda-intel.c (between opensuse 12.1 and 12.2)  cause the hang
problem
