Description

When I connect a monitor at one display port (fullhd) and a tv on hdmi (2.0, 4k), gnome control settings only list one dp/hdmi device is listed at sound settings, but audio is played in both devices if this one is selected.
This happens if I use kernel 5.3.7-1, no problem if I reboot in 5.2.17-1+b1. I'm using debian image kernels, gpu is vega20 (radeon 7).
