Ubuntu 18.04.2 LTS. Summary: Suddenly cannot output to more than one sound device. Details: Up until about a week ago, I could easily send different apps to different sound outputs (some to HDMI Output, some to Analog Stereo Output), using "pavucontrol". Suddenly, I can't. I can change between those two Output Devices in Ubuntu's settings. Each works perfectly fine, by itself. But the Output chosen in Ubuntu's settings, is then the only one available to applications. Any option to choose between Output Devices at app level (even in pavucontrol), just doesn't exist anymore. Gonesville. Now it's either all one, or it's the all the other. It's frustrating as hell. Can anyone help?
