No sound in various videos on YouTube

Posted

I have problem witch sound in YouTube. For example in this video https://www.youtube.com/watch?v=9eu2sF_kQ00 or this https://www.youtube.com/watch?v=3DcEMdNbZM4. No music but video works fine. In Project Spartan this video works without any problems. Any problem with codecs in Firefox?

Everything happens on Windows 10

Do you know whether your Firefox is using the built-in HTML5 video player or the Flash plugin? Typically if you right-click the player, the last line of the custom context menu will tell you wish player YouTube has served you.

If the HTML5 player does not work for you, there is an extension to force Flash on YouTube. (https://addons.mozilla.org/firefox/ad.../youtube-flash-video-player/) That might also be a feature of one of your video downloading extensions.

If you are using a Windows 10 Beta, or some sort of that, this may be your issue. You might not have correct drivers installed or so on. I would suggest going back to your old Windows version, and waiting on 10. If you don't want to do that, I would suggest finding audio drivers. With a little more info, I could go more in depth..

I have K-lite codecs and how i wrote before no problems on Project Spartan so this is must be a problem with Firefox. Perhaps Firefox have problems with be fully functionally on Win10.

Just might be. Firefox hasn't prepped for Windows 10 just yet, as it hasn't made full release. No further action can be taken as this is the answer.

If audio doesn't play on other sites (e.g., http://hpr.dogphilosophy.net/test/) you might also check whether Firefox is muted? On my system, I click the volume icon in the "notification area" of the Taskbar (also known as the tray) and then click a Mixer link. This shows the individual per-application volume controls. I have attached a screen shot for reference.

After changing player to flash i have audio. Volume level is good because only some videos don't have audio. So this is must be a problem with HTML5 and some audio codecs.

Thanks for help.
