Thanks for the report. Could you please test mozilla's official firefox
build (from https://www.mozilla.org/firefox/download/) and report
whether it's similarly affected?

Title:
Youtube hangs Firefox with HDMI audio enabled
Status in firefox package in Ubuntu:
Incomplete
Bug description:
If I have my output device set to "HDMI / DisplayPort - Built-in
Audio", playing a Youtube video on Firefox causes it to hang. It
initially loads fine, but nothing happens. The UI is still
responsive at this point, and I can scroll the page, switch tabs, etc.
However, if I then try to open a new tab or navigate to a new page,
Firefox hangs completely and I have to kill it.
If I switch the audio device back to internal speakers, everything
works fine.
This only started happening some time in the last week. Previously, I
observed a different behaviour, where Youtube videos simply wouldn't
play audio on HDMI unless I already had an audio stream initiated from
another app. It never hung the browser, though.
I first observed this on Firefox 76 beta, then 77, and now I have
confirmed it on the Ubuntu package of Firefox 75, all with a new,
clean profile.
Also, I *can* play audio on other sites like Pandora over HDMI. This
seems to be YouTube specific somehow.
