Hush: Android Auto Audio Fix

Android Auto is great, but sometimes you want Google Maps while listening to audio from an app that doesn't support Android Auto.  Unfortunately, there's a known issue with some vehicle's Android Auto implementation that causes Android Auto to resume the last Android Auto audio app you were listening to if you change the volume while listening to a non-Android Auto audio app such as YouTube. Nothing's more distracting while driving than going from a soft podcast on YouTube to deafening music on Spotify in a fraction of a second. Hush fixes this and other Android Auto audio-related issues by playing a silent audio track on repeat, leaving you free to safely adjust your vehicle's volume and enjoy your audio. Once launched, Hush will act as the currently active audio app, preventing Spotify/YouTube music from being resumed by AA whilst you listen to your favourite non-Android Autoaudio app. I developed Hush after putting up with this issue for years in my Toyota Camry. I've mentioned this issue to my Toyota dealer every time I get my car serviced, but they just say all updates have been installed and there's nothing they can do.
