Samsung Frame 85" 2023 with GTX 1050Ti GPU, HP G4 SFF, i5-8500, Win 11 Pro 26100.3194

TV signal, and audio cuts out (black screen) when using mouse arrow to drag scroll in side bar. Also gives a loud audible "click" as sound is temporarily cut out. ( Most probably whole HDMI signal is cut)

Black screen bug happens randomly with You tube with no mouse or keyboard action, but 100% repeatable with this website when scrolling :

Please advise how to fix

Hello! from this morning and alongside a new Firefox update i've been having graphical artifacts on Youtube/Facebook/Netflix. I've followed all the standard steps.

Disabled Hardware Acceleration. Updated Video Drives. Run FF in Safe Mode without plugins. Disabled Router level VPN and Ghostery.

Any ideas?

I'm running FF135.0 Geforce 572.16 Drives (30th Jan) 3070TI. Windows 10 Pro 22H2.

Здравствуйте. Последнее время заметил следующую проблему. При открытии некоторых сайтов, где есть видео или транляции, колесиком мышки открываю нужные видео или трансляции в новых вкладках. Ситуация следующая. Если не спеша открыть несколько вкладок, например 5, после перейти к ним, то нужно нажать в центре видео/трансляции "плей", чтобы видео стало работать. НО, если открыть вкладки (так же 5 или более) и сразу же переключаться на них, то видео будет автоматически стартовать. Раньше так и было при добавлении нескольких вкладок с видео, а после переключения на них, видео сразу открывалось. Теперь - нет. В настройках ничего нигде не менял, проверял как на версии браузера для пк на 133..., так и на последней 137... Отключал все дополнения, в настройках сайтов давал разрешение для автовоспроизведения аудио и видео. Хочу отметить, что такая проблема на многих сайтах. На некоторых же всё работает как и раньше. Также отмечу, что переустанавливал браузер с полной очисткой. Железо у пк хорошее, озу 32 гб. Никогда проблем такого рода не было. Прошу помочь с решением проблемы.

I've recently done a clean reinstall of Windows 11 and have noticed that, only for Firefox (134.0.2, build ID 20250120135430), a few videos playback without any audio, yet the same videos play with audio when using edge as a comparison. Most (if not all) of these videos did play with audio in Firefox prior to this reinstall.

Firstly, I'm pretty sure this is not a windows sound mixer issue since many videos on the same page and tab play back with audio just fine in Firefox. The same goes for it not relating to the Firefox setting 'Speaker selection', under (burger) > settings > privacy & security > Permissions because videos of different formats (or using different players) on the same page play back audio fine. The tab is not muted. Again, some videos on the same browser tab play audio fine; some of a particular format or player only play the video, while missing the audio (and where Edge plays the same video with audio).

Another common and potentially relevant issue I've seen is that, this being a 'Windows 11 N" install, it was initially missing the settings > system > optional features > Media feature pack, but that is now something I've successfully added. I should add that windows did report problems when I initially tried to add the media feature pack but, after a very long delay, it eventually appeared to succeed when I ran a couple of DISM incantations that I think ended with - "dism /online /add-capability /capabilityname:Media.MediaFeaturePack~~~~0.0.1.0"

I have the 'Play DRM-controlled content' setting enabled.

Comparing the Firefox vs Edge video playback on this video test page - https://tools.woolyss.com/html5-audio-video-tester/ I get the following results (don't know how to get it formatted/aligned correctly, sorry) -

                           FF vid    FF audio    Edge vid    Edge audio
av1-opus-sita.webm          Works     Works       Works       Works
vp9-vorbis-spring.webm      Works     Works       Works       Works

avc-mp3-sita.mov            Works     Works       Works       Works

And perhaps also relevant is that there's also a difference in the audio-only samples further down the table on the same page -

                   FF audio   Edge audio
audio-sample.mp3    Works      Works
audio-sample.weba   Works      Works
audio-sample.ogg    Works      Works
audio-sample.opus   Works      Works
audio-sample.flac   Works      Works
audio-sample.wav    Works      Works
audio-sample.m4a    FAILS      Works
ac192.mp3           Works      Works
spoonradio-hd.aac   FAILS      Works
audio.opus          Works      Works

Also, every 'v.redd.it' / reddit-video-player video plays the video fine but has no sound when using Firefox but plays both sound and video fine with Edge. Here's one for example - https://old.reddit.com/r/funny/comments/1i7y1nr/rock_paper_scissors/

I've seen lots of similar (but not identical) issues on Firefox video with no audio problems with suggestions a few things to try. In addition to what I've already mentioned above, I've tried the following without success -

- Restarting Windows - Restarting Firefox - Restarting Firefox with addons/extensions disabled - 'about:support' > Refresh Firefox - 'about:support' > Clear startup cache - (hamburger) > more tools > task manager > (click the little profile icon for the page playing the video) - I've checked the settings suggested here: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_check-some-firefox-settings

I realise it may be possible to side-step this problem by flailing around with more drastic work-arounds like trying a clean re-install of Windows or a full uninstall and clean of Firefox, but that doesn't really help figure out the problem, which leaves the possibility it could easily happen again to me or others when it might be something that can be more properly fixed or guarded against in Firefox itself, so I hope someone can suggest what might be done to home in on identifying the cause of the problem and so learn whether a more precise fix can be employed.

Firefox is no longer playing audio from the Internet. I am running Firefox on Windows 11, and have the latest update installed (10/29/25). What happened? How do I fix this.

I am 99.5% sure this is a Firefox issue, as I have no problem playing audio files stored in my computer, and no problem playing Internet audio using Chrome or Edge.

Help!

This issue came up in early April 2025.

Programs other than Firefox (e.g. Edge, Media Player) behave normally: when playing sound, if nothing is plugged into the 3.5 mm jack, the sound comes from the desktop's external speakers; and when an audio device (speakers or headphones) is plugged into the 3.5 mm jack, the sound instead comes from that device.

Where as Firefox will play using the internal speakers as expected, but when a device is plugged into the 3.5 mm jack, no sound signal goes to that device.

It seems then that the hardware is okay, and the problem must lie within Firefox, or within a Windows setting that is very specific to Firefox.

The sudden onset earlier this month may point to either a Firefox update, or (less likely) a Windows update.

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?

Can you guys check why your netflix account is getting logged out every time regardless of how many times you logged in and for prime video if you play any video i'm getting video player error, can you please check

This problem started yesterday. The sound in YouTube with Firefox is extremely low. As far as I can tell, the problem doesn't exist elsewhere. Other browers are OK with YouTube and other websites that have sound are OK with Firefox.

I reinstalled Firefox and rebooted the computer - still has the problem.

I'm using Windows 11 24H2 (home) on my desktop.

Sound on Rumble. It has always had an Enable Button with a bell, and clicking on that button has always enabled the sound at the videos I watch on Rumble. Recently, clicking on the button, adjusting the sound on Rumble settings in the video, and boosting the sound on my computer do not work. I'm hoping that can be fixed. Thanks in advance.

Maybe after update, or i dont know why, but now. when youtube (or any other videoplayer) in fullscreen - taskbar menu is visible (Is on topscreen). In google chrome problem is not repeats. I'm using StartAllBack app for classic start menu, but till that day all was fine. I checked on two devices with firefox - the same problem (StartAllBack or windows version wasnt cahnged). Windows 11 24H2

So Im currently trying to watch young sheldon on netflix, and im doing it through firefox, and it wont work, it says error code f7701-1003, thank you for your time.

why? WHY????

This is the link to the video that will not play in FireFox. https://www.swingtechnologies.com/UploadVideos/clarkj@pobox.com/S200629_019 B.mp4

There is an issue with MKV video playback with MP3 audio track in FireFox. The problem is that MKV video plays MP3 audio track without any sound. With AAC audio track the problem is that MKV video initially downloads whole video and only then plays it. In comparison with MP3 and AAC the benefit of MP3 is much better quality and it starts playing without downloading whole video like MP4.

It would be nice if you add support MKV video with MP3 audio playback.
