Playback and capture appear to work correctly with one possible caveats:
Item labeled "Front" controls the level of sound through the speakers. I would expect that it would only control sound from front HP. This happens whether Independent HP is on and off.
When you look at other controls, there are "Surround", "Center", and "LFE", and these are mixer controls for other two line-out jacks. In that sense, "Front" is corresponding to the same group, the line out jack.
You have an individual "Headphone" output. Isn't it obvious?

Not always, most labels are one word long and can be open to different interpretations. In alsamixer, ordering of capture controls is the following:
Master Headphon PCM Front Front Mi Surround Center LFE Side Line Boo S/PDIF S/PDIF D Auto-Mut Independ <Rear Mic>
and thus "Front" is next to "Front Mi" - that should connect at the front I assume - rather then to other outputs at the back. Thus it is very easy to get confused.
Here are outputs as specified in my MB manual and my attempt to pair them to items in alsamixer (Capture only):
MB description Alsa control (capture) BACK PORTS: Line In Line Boost (its boost only, I know) Front Speaker Out Front Mic In Rear Mic Boost Center/Subwoofer Center Rear Speaker Out ??? Side Speaker Out Side
FRONT PORTS: Headphone Out Headphone Front Mic In Front Mic Boost
There are two items that have not been assigned - Surround and LFE, presumably one of them should correspond to the "Rear Speaker Out" for which I could not identify ALSA control. Not being familiar with more than 2-channle audio, I do not know how to assign these.
