No sound when playing the steam game trailers

[Shalimar]

As of today I have suddenly no sound anymore when I want to watch the Steam game trailers! Up to yesterday it worked fine. The trailers are not muted (I checked it ;) ), sound is ok for all other programs. E.g. You Tube videos run well, games run well, only the trailers are "muted". I have seen that other persons have the same problem, but I have not seen any solution by now. Can somebody help please? My browser is Firefox, I have latest updates for all programs. Thanks a lot!

click on the speaker in your system tray and click on the mixer.
maybe it is muted there.

edit:probably not you call youtube a program ;)
I call it a website.

I just found out the solution xDDD: The volume slider suddenly was sent to the very left side (= no sound) - although I haven't changed nothing! When moving the slider a bit to the right side, the sound was back again :). Hopefully I could help somebody else with the same problem :).

rolling your middel mouse the wrong time can cause this.

Help~!

[Shalimar]

thanks for your help but i just found out the reason. somebody else pointed out that the volume slider was shifted to the very left side and when he shifted it a bit to the right side, sound was back again. and this was exactly the same case for me ;))). i had changed nothing at all (i "only" have a new monitor). but - at the end - everything is fine now. thanks for your quick reply!!

Yeah I also have the same problem. And I can't fix it. I keep hearing about this Steam-Settings-Audio and I can't see it anywhere. I went into speakers and nothing seems out of place. Move slider to left, to right, left it in middle..nothing.

I have the sound on monitor for game trailers but I don't wanna switch this everytime.

hello guys,

i suffered the same issues as mentioned in the previous / above comments n i've found the ultimate solution. theres 2 prime things that u need to do.

1st - ensure the steam video volume is turned on, bc as they've already mentioned its default to muted. steam should provide us w a feature to monitor the default sounds

2nd - i found this 1 myself by playin around n tweaking w the sound panel. in the bottom ride side of windows taskbar, right click on the speaker icon n tap on open volume mixer. there try finding steam client webhelper n unmute it. its the prime reason for the videos or game trailers still being muted in the app.

if u're using steam on chrome or another browser, there shouldnt be such an issue. for anymore help regarding this, u can add me on steam n dm me. i can further help u sort ya mic problems as well if there're any.

happy gaming!

THANK YOU. Finally sound is back in trailers. That Steam client webhelper was muted for whatever reason.

Again thank you very much for help.

I know this was a very old post from 2015 (10 years ago wow!) but I have to say this:

Was this really the best you were able to do to help this guy to find a solution to the audio issue? Basically you said "turn the volume on and Youtube is not a program"...
Wow...

Besides there is the Youtube APP for mobile and desktop then yes, Youtube IS also a program. And he didn't call Youtube a program, by the way.

Now, for the audio issue: I have the same problem now in 2025, I turned the volume up in my device settings, I also checked the "do not disturb" and it was off. Still the audio won't play. There might be something else to check but as for now I have no clue.

Hello again! I have found the solution, at least for me! Perhaps this will help others with this same issue! The problem was in the browser settings.
I'm currently using a Samsung tablet and Chrome browser, the Steam trailer videos were silent. The audio icon was ON and the audio bar was on the right side but still no sound was playing.
So I went to my Google Chrome three-dots menu then > Settings > (Advanced) Site settings > (Content) Sound. I turned ON the "allow sites to play sounds" option and there you go! Finally the trailer audio was back again! :)
