Asus P5LD2 SE AD1986A snd-hda-intel model and master volume control

Asus P5LD2 SE AD1986A snd-hda-intel model and master volume control

[EmIScA]

To get sound from my Asus P5LD2 SE motherboard (which uses AD1986A
codec) I had to set model=3stack manually using alsa 1.0.13.
It works well, but I have no master volume mixer control, why? There is
a Headphone control which don't control anything. Perhaps I can set the
volume using the Front control. Is it fixable? Can I  map Front as
Master? Can I create a master control that controls front, surround,
center and lfe together?

Ask me for other details if needed....
Thanks,
Emilio Scalise

AD1986A has no real master control.  That is, front, rear and CLFE
have separate volume controls but no master control indeed.

The PCM control affects all channels (intentionally done so).

Ok, I realized that... My problem is that gnome mixer, kmix, use 
headphone as master volume control.
I've read about the softvol plugin, how I can setup it to simulate the 
master control?
Can I rename a mixer control?

Or you could adapt the patches I just posted to bind the existing
controls :-)

I'm not sure if there's any advantage, if your PCM control affects
all channels; mine only affected front.

I've not seen any posts yet...

Depends on the codec chip design.

When you can adjust the volume of each channel at the output PIN (or
in an earlier path), it's rather annoying that "PCM volume" changes
only front output.  This will end up with 3 PCM volume controls for
front, rear and CLFE, which are complex but useless, IMO.

Weird!  I got a copy back, and it shows up in the sourceforge archives
(Subject: Ganged volume).  Let me know if you want another copy.

As far as I could tell from the block diagram for the vt1617a, the
master volume affected the output of only the front channel, and the
PCM volume affect the input of only the front channel.  I'm not
entirely clear on why that's useful :-)

Maybe filtered by a spam filter.  Could you resend a copy to me?

Of course, it's completely different from AC97 codec chip.
In the case of AC97, it is _defined_ to behave the PCM affects only
front.  But HD-audio codecs are not.
