Firefox Community Forum

Good evening Mozilla,

Well I am facing an issue, no sound coming from any website like netflix or youtube or prime from mozilla browser.

Could you please fix it for me.

Regards

I've seen many questions about this matter over the years, and thought I'd been lucky. Every link containing a .m3u file opened in my media player, WACUP. However ... after an update to version 143 it suddenly didn't. .m3u links opened as a text file in the browser window.

We have five windows 10 workstations in the home, and this happened with all of them.

I write webpages for a family intranet, and several thousand tracks are available for playing, so that was messed up too.

These are the steps I followed - unsuccessfully:

• Bulleted list item Checked file association settings in Windows 10. .m3u was associated to WACUP, my media player.
• Bulleted list item Checked file actions in Firefox. .m3u files set to open in WACUP.
• Bulleted list item Added the type="audio/mpgurl" in the anchor link for webpages I make.
• Bulleted list item Changed the default download panel in FF settings to "Ask". I could then get it to ask me to save or open. "Open" worked, as it this is tied to the system default audio player - nothing to do with FF.
• Bulleted list item A few other frustrating, but eventually inconsequential solutions that were in the realm of "I wonder if ...?"

So ... after all of this and a lot of investigation I noticed something interesting: All my playlists were in the format with just a listing of the filename, which as mentioned had been working for years:

Example "01 Queen - We Are The Champions.mp3".

Yet a playlist made in VLC had a different format: example,

"#EXTM3U

1. EXTINF:-1,01 The Beach Boys - Help Me Rhonda.mp3

01 The Beach Boys - Help Me Rhonda.mp3 "

SOLUTION

Having far too much time on my hands, I experimented with this, dissecting the various components of the playlist, and eventually found when adding "#EXTM3U" as the first line in the playlist, Firefox opened the playlist in WACUP once again when the link was clicked.

New playlist entry:

1. EXTM3U

01 Queen - We Are The Champions.mp3 02 ... 03 ... etc.

I've left the "type='audio/mpegurl" declaration in the link.

I don't know why this happened, but I hope somebody finds this useful in the future.

So now I have several thousand playlists to edit, although Notepad++ will make this easier, but by no means quick.

Lost my audio on Firefox. All movies and web site videos SILENT

Strange exceptions: e.g., can't ear video on youtube.com; BUT, CAN hear it if web page has LINK to YouTube!?!? SOME Twitter videous have audio; others are silent

How do I turn Firefox audio back ON?

I am using Pop OS. Videos are not playing in firefox. In youtube it shows loading infinitly. In reddit all videos become green. I tried playing a downloaded video it also become green. These are only happening in integrated mode. If I use hybrid graphics mode all works good. I attached the about:support page and about:config page.

about:config page link about:support page

These files are taken in integrated graphics mode.

Just built a new PC and using Win11. I like to have a pinned tab in Firefox playing some kind of media to have background noise. Since new build, whenever I am not 'focused' on that tab and doing other tasks, audio from that tab will cut/fade in and out.

I've been working on this for 16 hours. I've googled, binged, even yahooed. No answers. Checked and rechecked all settings, both system and browser. Uninstalled/Reinstalled *many* applications, including Firefox. My OCD won't let me rest till I have this solved.

Thanks for the help.
