@beeshyams suggestion worked: Google knows where your phone is, even if you don't.

From [another user][1], you can also do it with ADB:

    adb push t.mp3 /sdcard/
    adb shell am start -a android.intent.action.VIEW -d file:///sdcard/t.mp3 -t audio/mp3

> (Playing a video file the same way or starting youtube (`adb shell am
> start -a android.intent.action.VIEW -d
> https://www.youtube.com/watch\?v\=oVQqmH4ufCQ`)) will not produce any
> sound if the device is locked it seems like)
