Using the desktop app on a Mac, and I'm looking for a way to choose my Bluetooth speakers as an output source. The way I use it now, is that I connect to my Bluetooth speakers, but then all of the sounds on my laptop, including Pandora go to the speaker. This is not ideal because I don't want to hear sound effects from my other apps. iTunes has a way of chosing the audio output, but I downloaded and installed the Pandora app, and I can't figure out how to do that. Is it even possible?
