Hi, @Niiky. How are you doing?
From where are you sending this command?
I created a virtual device that uses the mediaInputSource capability, and I can send the command through Postman as follows:

{
    "commands": [
        {
            "component": "main",
            "capability": "mediaInputSource",
            "command": "setInputSource",
            "arguments": ["AM"]
        }
    ]
}
