Trigger for changes on device audio input

Questions & Suggestions
1

Hi!

I have a macro that is triggered when there are changes to the device audio output, but I have seen that there is no trigger for changes on the audio input.

Is there some way to achieve this? Or maybe this would be an improvement for KM?

With the lack of that specific trigger, you could run a periodic macro that checks the audio input device for changes, like this:

I don't own any USB-based audio devices, but if you do, then I think you should be able to detect their connection and disconnection using the built-in Keyboard Maestro USB Device trigger. That should work with either input our output devices. But they have to be USB devices that you physically connect and disconnect, I think.

Thanks a lot! I think I'll try that, although I'm particularly careful on doing macros that execute every few seconds. I hope that this could be an improvement for Keyboard Maestro.

Thanks, it's not an USB device, so that trigger would not work.

@peternlewis Hi! Any chance to include it on a next version of KM?

Unlikely.

It requires some sort of event for it to be a trigger.
