Yes.

pulseaudio is already the newest version (1:15.99.1+dfsg1-1ubuntu2.1).

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Does the problem also occur with https://nightly.mozilla.org?

Didn't send steps to recreate because it happens with every site.
Go to youtube.com
play video
no sound

Interesting. The nightly build I downloaded appears to be working.

Thanks!

Does the problem still occur after a reboot?

(#0) Error: GFX: R(#0) Error: GFX: RenderThread detected a device reset in PostUpdate
(#1) Error: Failed to make render context current during destroying.enderThread detected a device reset in PostUpdate

Does the problem only occur after suspend & resume?

The problem has persisted for about a year. I have upgraded Ubuntu and upgraded Firefox several times.

If I were to guess, I'd say it had something to do with SNAP.

The severity field is not set for this bug.
:jimm, could you have a look please?

I don't see errors in what we've detected and attempt to use. It's also interesting that downloaded Nightly works. I'm not sure how to progress here as we do not have STR.

Since I can recreate it right now, can't I be of assistance?

I have the same problem as the reporter. Firefox and Firefox Beta doesn't play sound, Nightly and other browsers does. Kinda strange

I found a fix, which worked for me. For Windows 10/11 under Windows 10/11 Settings -> System -> Sound -> Volume Mixer -> Reset to default settings.

So eventually did Windows set a null value to the output value of firefox and that's why it doesn't play any sound.
This worked for me.

This is not a windows bug.

No, since Ubuntu, to my knowledge, doesn't have anything like the sound mixer, there's not really a way to test your solution.
