Thanks for the report Benjamin. This sounds similar to https://bugzilla.mozilla.org/show_bug.cgi?id=1719968. Could you test on the affected machine with an upstream build (as downloaded from https://www.mozilla.org/en/firefox/download/thanks/), and let us know whether you're observing the same problem? If so, can you comment on that upstream bug?
Also, is the XPS 13 also running Ubuntu 20.04, or a more recent release? ** Bug watch added: Mozilla Bugzilla #1719968 https://bugzilla.mozilla.org/show_bug.cgi?id=1719968 ** Changed in: firefox (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1950533 Title: Logging into Discord with DRM streaming in other Firefox tab breaks sound.
