Hi,
as sndev said, the keybinding code in mixer was taken from the language module.
The bindings in the mixer modules need at least one gadcon instance of the mixer
in order to work. The mixer initialize is configuration only if an instance is
created.
Once the configuration is filled with the right mixer then the keybinding can
works.
So you need to put the mixer module in a shelf to have keybindings working.
I could have move a part of the configuration code in order to make it works
right
after the module is loaded. But at that time I wasn't really seeing the point.
The other issue can be because of the default value of the keybindings.
I used some default keycodes for the media keys. Since I don't really know if
there's
some kind of specs making keyboards. I've asked a few people with different
keyboards to give me there keysymbols and keycodes for this media keys.
None of them had a keysymbols and the keycodes was the same.
And so I set the keybindings by default on keycodes 160 174 and 176.
It might not be always that values but you can change them on E keybindings
config.
