Bug Description
I have two monitors hooked up to an AMD RX570 via displayport. In the sound settings they appear as "Ellesmere HDMI Audio [Radeon RX 470/480/
Originally, I had upgraded to the beta from the command line in 19.04. I had not experienced this issue in 19.04, but upon first booting into 19.10, I had to switch output device back to line out. A fresh install of the beta iso gave the same result (one of my monitors connected to my video card was selected by default). Note that my monitors are Dell U2415s but they do have line out jacks.
