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?

After installing update 147.0, when watching videos on YouTube or twitch, artifacts appear on the monitor and an error message appears stating that your driver has been restored to its default value. In version Firefox 146.0. There were no such problems, and in general there were no such problems. But my graphics card is not a new AMD Radeon R7 250X 1gb. Version 147.0 states that "Improved video playback performance on systems with AMD GPUs by enabling zero-copy playback for hardware-decoded video where supported, bringing them to parity with Intel and NVIDIA GPUs." I think the reason here is the incompatibility of either drivers or with encoding support on old video cards, I hope that the developers will fix this problem for me.

Since a few days ago, Firefox has been struggling with the likes of youtube, twitch and other streaming videos where the the videos will constantly freeze up, forcing me to use a different browser in order to watch videos.

Nothing has changed (ie I have not added any new extensions), and have also done a flat re-install of Firefox to no avail (as well as trying firefox without the Mozilla VPN on to see if that did anything).

Hello Mozilla Support Team,

from yesterday playback speed on youtube is not working. When I open the same video with Edge playback speed is available.

Could you please check and rework?

Thanks in advance.

Many greetings Stefan

I am running Firefox 144.0 on kubuntu 24.04.3 LTS I have lost sound on Firefox. I have opened the same sites in Chrome and the sound is working fine. It's only in Firefox. I have tried several sites including Udemy, YouTube, and radio programs, no sound from Firefox. The problem started in the middle of a Jit.Si session. All of a sudden the sound disappeared. I thought that restart Firefox would help, then restart the computer would help. But the problem has continued. The speakers is turned on the volume is up, just not a sound from Firefox. What to do?

Facing these issues on video/educational platforms other than YouTube. I am not facing either of these issues on other browsers like Microsoft Edge, on the same network. Please let me peacefully watch my educational videos, else I'll have to switch to other browsers and encourage others to do the same. I have a lot of respect for your open-source community-based browser, but such errors are causing intolerable pain. PLEASE RESOLVE ASAP.

Particularly on US news sites, inline / spot videos still auto-play despite the FF preference set to block audio and video. Mercifully, audio isn't playing. This seems to be a fairly recent problem since the last couple / few updates; not really certain.

YouTube videos are choppy in Firefox, despite trying solutions like clearing the cache, disabling hardware acceleration, and using Safe Mode. I’m using Windows 10 with the latest version of Firefox. What can I do to resolve this?"

I cannot seem to get playback with Firefox browser for either Tubi TV or Pluto TV anymore. Have uninstalled and reinstalled Firefox, have tried to just refresh data yet still no playback.

Some videos work perfectly fine, however for some videos audio lags behind the video. The same video file perfectly works in Chromium as a control test. Example file is MP4, inside was initially h264 video with AAC audio, for test I re-encoded video to be svt-AV1 with AAC / flac as well - no difference, audio still lags behind. Local players (mpv) and Chromium works perfectly. No plugins which can affect it - for testing disabled them all. I really try hard to like Firefox but this thing is a real bummer. Any ideas what can be causing? P.S. I tested both firefox compiled from source and binary package provided by my distro. Linux system if that matters.

For the last two years the issues with video stutter have been worse and worse for me. I don't know if it is because of a different codec the video is using, but if it was I would expect the fans to ramp up from trying to decode it. Instead, my laptop stays always silent, but the video laggs like crazy when I want to play it at native 1440p.

I cannot view or change the video codec, since the current issue happens on a platform (herohero.com) other than youtube.

Hello,

I am a new firefox user and would like to use it 100%, but have been running into a few bugs. This one I have been unable to find this issue myself, so thought I would ask here. I use Qobuz to stream hi-res music up to 24bit/ 192kHz. Some albums do not have sound at that resolution. The file will load and timer shows the song is playing, but there is no audio. I can change the setting to stream at 16bit/44.1kHz and then I get audio. Again, this does not occur with all albums, some will stream at hi-res and some will not. An interesting note: the same file with no audio at hi-res on firefox will have audio at same resolution setting on chrome. The only thing I can think of is chrome is reducing resolution in the background, or maybe a DRM issue? I do have "Play DRM-controlled content" checked in firefox settings.

p.s. I am aware that streaming music through a browser is not necessarily the best way to listen to hi-res music, and my ears may, or may not hear the difference between the 16bit and 24bit. However, the issue is the functionality, or lack of.

Thank you in advance for any insight.

I have a gpu rtx 50 and recently decided to use rtx super resolution to improve watching online videos but I can't make it work on firefox, I'm currently using the DEV Edition x64 latest version HW Acceleration is enabled and I also tried modifying via about:config the lines: media.peerconnection.video.use_rtx gfx.webrender.overlay-vp-super-resolution gfx.webrender.super-resolution.nvidia

It still doesn't work! tested in the other versions of firefox and it also did not work Using brave, chrome and edge..works normally without having to do anything. Does anyone know what it can be???
