Bug Description
Ubuntu 21.04, Firefox 88.0.1.
The video card (Radeon RX 570) has HDMI and DisplayPort outputs. DisplayPort is used to connect to a monitor that also has loudspeakers. The PC also has headphones output.
In Settings/Audio, the box Output has a dropdown menu that lists, among others, Headphones - Family 17h and HDMI/DisplayPort 5 - Ellesmere HDMI Audio [Radeon RX 470/480/490 / 570/580/590].
When that dropdown is toggled, all applications (e.g. Video) change the audio output, so the application audio can be heard on the selected output. With the exception of Firefox, that always sends its audio output to the headphones, irrespective of the dropdown.
