Query regarding external alsa plugins

[Pharaoh .]

Hi

I am writing an external IO type plugin for my board since my audio driver
is going to be a user space driver
i.e. no alsa kernel driver because of some technical reasons. My pluging
works okay and now I want to provide
a mixer control interface like volume control and playback path  selection
etc.

Is there anything like mixer plugin etc which can be intergrated with my
existing plugin? Can I get a test code
somewhere?

Regards,
Sandeep.

To further elaborate my question , when I do an aplay the control comes to
my plugin and I can play the audio samples, but I want to some mechanism
using which,

#amixer -D my_control_plugin cset numid=1 100 //say volume control

should also come to my plugin, a control plugin may be? How do I do this, I
dont know any way to specify the plugin path while using amixer command.
