Hello,

Where is the ALSA mixer API documentation? I looked at http://www.alsa-project.org/alsa-doc/alsa-lib/mixer.html, but that only says "Mixer interface is designed to access the abstracted mixer controls. This is an abstraction layer over the hcontrol layer".

The mixer interface isn't well documented than others, unfortunately.

I'll stick with OSS emulation until someone can be bothered to document ALSA then.

You can find brief description of each function and data definition in the module section

http://www.alsa-project.org/alsa-doc/alsa-lib/group___mixer.html

and "Simple Mixer" section there.
