I don't have such plan.

In my understanding, such functionality should be in user-land. Drivers 
should just transfer samples from/to application to/from devices, should 
do nothing others.

(...To tell the truth, I want to keep drivers as simple as possible for 
maintainance reasons ;p)

Exactly. For this issue, I assume that users utilize 'plughw' plugin. 
Actually I test drivers with aplay/arecord and this plugin.

But recently, most users use Desctop Environment such as GNOME, KDE. The 
sound envoronment of them are already based on PulseAudio. So I want 
PulseAudio to adjust the mismatch between applications and actual devices.

I hope it. What should I do for this idea?
