Firefox Stopped Playing Sounds

For some reason, Firefox now can’t seem to play any sounds. Two days ago I was streaming XMRadio all day just fine, and then when I booted up this morning…nothing. There is no sound from YouTube as well, but all video’s themselves do play. I tried under Chrome and everything works just fine. As a point of clarification, the output I am referencing are the speakers that are plugged into the onboard sound. I have followed the suggestions on the Firefox help page with no luck

I don’t remember seeing where there was an update the other that would have triggered this behavior, but I can’t say for sure…

Any idea’s?

Any message if you run FF from terminal ? Is it downloaded from mozilla website or suse package ?

When going to YouTube, I get:

But Sirius doesn’t give the above but does give:

I get same error on YT but I hear sound.

(apulse because I don’t have pulseaudio installed)

Did you try change pavucontrol settings ?

No. When I do run it, I see Firefox in the list, but the slider bar is dimmed out like it isn’t receiving and data from the application. I say that because right now, Chrome is playing music, and it has the slider bar lit up. Does that make sense?

Usually it is dimmed if it is muted.
There is a sound icon on the right end of the slider have a look at it. It might just be in mute mode.

Tried that with no luck. If I had to guess, I would say that Firefox is making a connection to the sound system itself, but it just isn’t producing any sound. Guess I will have to wait for the next Firefox build to see if that fixes it, but I don’t have much hope because I don’t believe Firefox was updated to trigger this.

If it’s only firefox having a problem with your audio, then your audio looks good.
Where did you got your firefox because firefox here is working great in sounds.
What if you rename your /home/user/.mozilla/firefox and try to run firefox again

I am using Firefox right from the openSUSE repos. I just tried the renaming of the directory with the same results.
What is weird is that one day it was working just fine and the next…nothing. It’s like I mistakenly turned something off, but I just don’t know what that could be.

I do see this in Yast for the Firefox package:

| Tue 18 Oct 2022 08:00:00 AM EDT
|
| martin.sirringhaus@suse.com
| - Firefox 102.4.0esr ESR
Placeholder changelog-entry (bsc#1204421)

  • Added mozilla-partial-revert-1768632.patch to fix build on i586
    |

So I believe it was sometime time after the 18th that the issue arose. Any idea’s where I should post this possible issue with the build?

You are missing the ffmpeg library. Install


sudo zypper dist-upgrade --from packman-essentials --allow-vendor-change
sudo zypper install --from packman-essentials ffmpeg

Please disregards this, for some reason I was reading that as 08-Nov.

Open Firefox and play content that should play sound,
Click the volume icon in the Windows taskbar.
Click Mixer. The Volume Mixer window will appear.
Make sure the slider for Mozilla Firefox is not muted or at the bottom.

Useless reference to Windows. About to nuke and ban.

Just received an update to Firefox and still have no sound. Is there some global setting in either Firefox or KDE that kills all sounds for that particular app?

Please follow instructions as per hui’s advice in post #13.

****…I missed that message. Thanks for catching that. I will try it out.

Before I install ffmpeg-4, is this going to cause any issues? I can’t seem to find the difference between the two packages.
