Approximately 2 years back, for a short period of time, FireFox let you choose an audio output device in video conferencing web apps, through the web app directly. This seems to be gone now, but I'd like to turn the feature back on. It's very problematic to have to change your default audio device for video calls, as your computers sound effects and whatnot will also play in your headset as well, where as before, all you got was the audio from the video call in your headset. Is there a way to turn this on again? Owl Practice (one of the VC web apps I use) still shows the different output devices, but regardless of which one you pick, it always comes out the default device. For a while this feature actually worked, but now it doesn't. Is there a setting I can change? Maybe in about:config? Thanks!
