That's a great question, but a better question might be "Can I link ...".
Probably, if you ask the customer service of the speaker makers they'll say that you should ask the maker of your laptop. And when you aks the customer service of your laptop maker, they'll say you ask the maker of the speakers.
I just checked on my Dell laptop. All the keyboard applet in Control Panel says is that it is a standard PS/2 keyboard (although it isn't) and it doesn't even mention the volume keys next to the keyboard. But maybe your control panel applets (for sound, keyboard or bluetooth) have more options?
I recently bought some bluetooth speakers i am using with my laptop now.
Everything is working very well but i cant use the volume buttons of my laptops keyboard to adjust the volume that come from the speakers.
If i use the buttons it shows the volume going down but it is not working with the speakers only wit the build in laptopspeakers.
when i click the speaker button right down of the laptop screen it shows the volume of the speakers (bluetooth audio device) and i can change the volume of the speakers there.
My question: How can i link the volume quickbuttons of my laptop with the bluetooth audiospeakers?
