How would I set the volume on a chromecast audio?

[dk253]

Hey, Thanks for the library!
I'm trying to set the volume on a Chromecast Audio. Actually I'm trying to write a web app to control all the volumes on all of the chromecasts at once. How would I use your lib to do that?

Thanks!

if(typeof volume !== 'undefined') {
		  
			if(volume > 0){
				var obj = { level: volume/100 };
			} else {
				var obj = { muted: true };
			}
			
			  client.setVolume(obj, function(err, newvol){
				if(err) {
					console.log("there was an error setting the volume")
					node.error("Chromecast error: there was an error setting the volume");
					msg.error = "there was an error setting the volume";
					node.send(msg);
					return node.status({
					  shape: "dot",
					  fill: "red",
					  text: "error: there was an error setting the volume" 
					});
				}
				console.log("volume changed to %s", Math.round(newvol.level * 100))
			});
				
		  }
