Separate control of AC97 audio connectors?

Hello,

I am trying to control (disable/enable/set the volume) of the front

and back audio connectors of an AC´97 audio device.

Right now when I plug a speaker in the back connector and a phone in

the front connector, both play audio at the same time. I would like to

be able to control that, as well as the mic levels.

Some documents about the AC´97 architecture indicate that this would

depend on the software and drivers that are installed. But I have

upgraded the driver and still am not able to do it.

Do you know if this separate control for the AC´97 hardware is

feasible? How can I do that?

Thanks in advance,

Inacio.
