On my ThinkPad X220, I’ve been able to use two out of the four volume control buttons in Haiku without issue: the mute speaker and mute mic buttons. However, the Volume Up/Down buttons don’t seem to function, and I can’t seem to find a method of mapping them to any functions.
The Keyboard and Media preference panels don’t make anything obvious to fix. Is there somewhere I can map these two buttons so I can have volume adjustment control?
Just out of curiosity, how hard would it be to implement that, could it be a gsoc project or some fundraising? I am not approgrammer, i cannot estimate the effort.
Not hard, just time consuming. Mainly in the parts of discussing how to do this properly. There is already progress towards this in the sourcetree and gerrit.
