This thread suggests some workarounds but not a real solution to monitoring system audio as a trigger.
I was wanting to surface this question again to see if any solutions are available 3 years later?
I want to monitor sound from a Safari Tab and trigger an action if the tab is producing no sound after a delay.
Can KM maestro monitor sound levels from Safari or from the system in general to trigger an action?
Could also use a 3rd party program if anybody is aware of one that could trigger the KM action via AppleScript or Python, etc.
I'm looking for this also. I want to be able to detect what source is producing the audio coming from my speakers as any point in time so I can mute the source. Currently I want to know if audio is currently playing from Apple Music or Safari but other sources might come into play like Zoom or other apps that produce sound.
