Nothing about this is turnkey. It's a mess of protocols, firmware and apps, but if you're the right kind of nuts, keep reading.

As it turns out, it is not trivial to control the audio volume of an Android device using ADB. At the time of writing, the only way appears to be using the service tool. Actually, the service command allows to "connect" to a number of services (104 on Android 6.0.1) and invoke functions. Not knowing much about this tool, I managed to completely mute all sounds and speakers of my Nexus 5, and I was stuck without any sound for quite some time. I did not find a way to unmute the sound from within the system UI, so I got to dive a little deeper into this.

If you know which service you want to use, you then need to find its interface declaration. The command

service list

gives you a list of all services with the associated interfaces, if applicable:

	Hi All!

	I've recently launched a tool that wraps many of the commands here with a user interface. This desktop application is currently available for macOS. There's a roadmap outlining planned features for the near future.
	Feel free to request any features you'd like to see, and I'll prioritize them accordingly.
	One of the most important aspects of this application is that every command executed behind the scenes is displayed in a special log section. This allows you to see exactly what’s happening and learn from it.

	Here's the link to the repository: https://github.com/Pulimet/ADBugger

	App Description:
	ADBugger is a desktop tool designed for debugging and QA of Android devices and emulators. It simplifies testing, debugging, and performance analysis by offering device management, automated testing, log analysis, and remote control capabilities. This ensures smooth app performance across various setups.
