Same here. To be honest, it’s never worked well. Even when I had it working, it was always picking the wrong output device and required re-configuring every time I would take my mac out of sleep mode. The looping audio killed it for me. Every time I opened it after that happened, I just got an annoying loop from when it went tits up. I just deinstalled and am now using Boom.
This is entirely frustrating. Roll back, sound returns. But at some point, it stops working. So I upgrade and it comes back. Then it goes away, so I re-install and it comes back. Next time this happens, I need to look in console to see what processes are related to this.
