Integrate gphoto2 audio cap

[Houkime]

I have a pretty low-end mic.
So low-end that even my camera can capture better audio.
gphoto2 has an ability to capture audio - I checked.

It's only logical to try to capture audio in addition to video.

As far as I know at this moment gphoto does't can how to capture audio and even real video. gphoto2 --capture-sound is a stub, and this function is not implemented in any camera driver. And when I try to use it, I get the following message:
$ gphoto2 --capture-sound
ERROR: Could not capture image.
ERROR: Could not capture.
*** Error (-6: 'Unsupported operation') ***

Does this work for your camera, or can you give a link to the information that this function is implemented?
