Public bug reported: 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. ** Affects: firefox (Ubuntu) Importance: Undecided Status: New ** Tags: audio pulseaudio sound -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1928624 Title: Firefox does not honour PulseAudio settings to decide what audio output to use Status in firefox package in Ubuntu: New Bug description: Ubuntu 21.04, Firefox 88.0.1.
