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.
