Soundcaster

macOS menubar app to cast system audio to Chromecast.

Installation and usage:

Download and install Soundflower v2.0b2 (if you have a previous version, follow these instructions to uninstall it and then install v2.0b2).
At this point, I want to say download the newest version of Soundcaster, unzip it and drop it into your Applications folder. However, doing this, even though it’s an exact copy of what is compiled, produces an empty list of Cast devices, whereas my local copy works fine. So all I can suggest is you manually compile the app yourself :-/
If you want it to start automatically with your computer do this.
The first time you run it, it might say it is damaged and can't be opened. If so, you will need to run sudo spctl --master-disable, run it, and then sudo spctl --master-enable. You only have to do this the first time.

Development

The app includes node_modules packaged, these are not included in the repo. An npm install will generate them. The app is built with XCode as normal.

Known issues

Unexpected behavior when trying to cast to a Chromecast while it's booting (or just booted). This is an issue in the chromecast-osx-audio module dependency.
