Alsa Mixer api documentation.

[Chuckles <chuckleberryfinn@gmail.com>]

Hello,
      I am trying to find a clear example, tutorial or guide to the
alsa mixer api. The documentation generated in the doxygen
subdirectory of the doc subdirectory of the alsa-lib package is not
very clear. The index page of the library api documentation does
contain a link to some mixer info:
                            
                             API Links
                ........
                Page Mixer interface explains the mixer controls API.
                ........

But that link contains:

               Mixer interface

             Mixer interface is designed to access the abstracted
mixer controls. This is an            abstraction layer over the
hcontrol layer.

General overview 

And that's it, there is nothing under the heading General Overview. I
have found some of the method prototypes are documented but they are a
bit ambiguous in regards to the actual functions they perform.
(snd_mixer_first_elem) Michal Kochanowicz previously sent an email
about this with subject
'Mixer programming - is there any documentation available?'
So...is there? If anyone can even give me a simple "open mixer, set
pcm to 50%, close mixer" example that'd be great.
Thanks for any and all help,

Cathal
