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.

I can select the video on the thumbnail and then the thumbnail says playing but nothing is happening. No video and no audio. Videos on all other sites work normally

Since to your "upgrade"to firefocx on my computer I can no longer watch youtube or iplayer videos. Pease say how I can downgrade my version so as to be able to see these.

频繁使用视频快进/后退，会导致Windows 音频设备图形隔离（audiodg.exe）内存泄露，

复现： 浏览任意视频，使用方向键左右频繁切换快进/后退， 可以看到内存逐步增加，退出浏览无法得到完全释放， 若长时间使用最终会导致内存泄露，如播放列表频繁使用快进/后退 // 已尝试更新相关驱动，关闭部分音频相关功能，无法得到解决，目前推测是firefox问题， 使用microsoft edge尝试复现，无此问题

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

[redacted] problem you [redacted] im having issues with the video and ads as all of my apps are disabeld nothing works and firefox it self causing probs and no one is helping out.

no matter what I try I cannot get any content from HBO max, crunchyroll, or spotify to play. I feel as though I have tried every troublshooting step. In firefox 140.0.4 64 bit on windows 10 I have:

-turned DRM off and on -disabled and re-enabled widevine -disabling all extensions -try in a private tab -turning off tracking protection -clearing cookies/cache/site data -uninstalling and reinstalling firefox -trying on firefox nightly -trying on other firefox based browsers zen, librefox same issue. chromium based browsers and firefox on my windows 11 laptop play drm content like normal -manually installing older version of widevine -changing useragent to chrome(this triggered cloudflare and would not let me pass) -making another user in windows and trying there

the error i get on crunchyroll is code: DRM-0 and on spotify it loads but the play icon does nothing. in hbo max i get error code 1k-0003

At this point I don't know what else to try, If there is not another solution I probably try to just switch to brave browser or wiping this pc and reinstalling windows.

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?
