@zing Many thanks again for more info. I guess ill have a dive into whats possible with the event scripts in EmulationStation.

Thanks for helping me understand more about the system, hopefully I can work something out after some reading.

Fingers crossed.

@zing Many thanks for the detailed response.

Yes I am not using a TV, just an old laptop sort of repurposed as an arcade cabnet I guess thats easy to pack away or move into another room. Screen speakers etc all in one.

I had a look through the Hotkey+B menu and can see gain control but no master volume control.

I guess what I am looking for is a way to have the underlying os map a command to the laptop keyboard?

So that I have the same volume control of the laptop if it were running a normal desktop OS.

What is recalbox built on?

I have recalbox installed on an old laptop and am looking for a way to setup volume control.

I can ssh in and use amixer set commands successfully, just stuck trying to find a way to map these to the laptop keyboard somehow.

If anyone could nudge me in the right direction it would be appreciated.

Thanks!
