commit f741c8a1f649379f8f3eb81119df2676c46075cf Merge: d821c1e 164a7ad Author: Takashi Iwai tiwai@suse.de Date: Fri Jan 18 18:30:00 2013 +0100
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.
Try
speaker-test -D hw:0 -c 8 -t wav

Your can also use early patching or hda-jack-retask
1)the three stacks model by change the pin default of the black, orange and grey jacks as [N/A] to test the channel mode switch
2) retasking front Mic Jack as another front headphone jack or vice versa
