As you have not provided any output of alsa-info.sh , it is impossible to say this case is a regression or not
Apologies. ALSA information can be found here: http://www.alsa-project.org/db/?f=e0b199a8e8de35452f761359e753f0f668bb9551
In addition, the original bug I submitted can be found here: https://bugs.launchpad.net/bugs/655351
There is a full hardware info dump as made by apport alongside that.
If the driver cannot find the [Pin Complex] Speaker at Int when you select
model=auto. it assume that it is a desktop instead of a laptop
The machine presenting the issue is indeed a desktop, not a laptop.
-d
According to the output of alsa-infos.h, the motherboard seem has 6 audio jacks and spdif out at the rear panel , green/pink jack at front panel
In theory the model should be 6stack-dig but hda-emu seem has several error messages when using your codec-info.
The ALC888 series are high-performance 7.1+2 Channel High Definition Audio Codecs providing ten DAC channels that simultaneously support 7.1 sound playback, plus 2 channels of independent stereo sound output (multiple streaming) through the front panel stereo outputs. The series integrates two stereo ADCs that can support a stereo microphone
There are five volume controls and mute switches In the Block diagram (page 5 of alc888 datasheet) and the driver had created
The driver only implement stream_analog_alt_capture, but the 2 channels of indpendent stereo has not been implemented if you look at the comment in patch_realtek.c

Headphones don't mute master sound is quite different from your previous posts and David 's post
You expect all the 4 audio jacks in the rear panel should be muted when the headphone is plugged in
This first appeared on my upgrade to 9.04
http://git.alsa-project.org/?p=alsa-kernel.git;a=commit;h=2134ea4f37d36addbe...
since the virtual master volume control and playback switch is to allow codecs that have no real hardware master volume registers
The virtual master playback switch of reatek codecs 's slave contains the following switches
static const char *alc_slave_sws[] = { "Front Playback Switch", "Surround Playback Switch", "Center Playback Switch", "LFE Playback Switch", "Side Playback Switch", "Headphone Playback Switch", "Speaker Playback Switch", "Mono Playback Switch", "iSpeaker Playback Switch", NULL, }
You should notice that the Left/Right balance control of Kmix was removed because both left/right channels are increase/decrease at the same time when you moved the volume slider of the virtual master volume control
Your problem can be solved if someone implement stream_analog_alt_playback for the headphone so that you can use the new playback device to play audio to the headphone only
/* FIXME: setup DAC5 */ /*spec->stream_analog_alt_playback = &alc880_pcm_analog_alt_playback;*/
This feature is not new , the alt playback device is /dev/adsp in the oss driver ,
PA will has two sinks for the internal audio , you just switch the profile to the independent headphone profile or use the sound preference to switch the audio stream from analog-output sink to independent headphone sink
