Audio doesn't work only in Firefox. In the mixer it appears like Firefox's using SPDIF output instead of speakers, but in the system (win81) speakers is default

Posted

Hi, I.ve a Win 8.1 64 installation. Everything's working and also audio in Mozilla form youtube or other sources. But when I play Vimeo videos it doesn't work Opening the mixer, selecting the output "speakers" nothing happens; igf I select SPDIF output, Firefox's audio bar seems move up and down . But audio default in win8 system is speakers. What happens? It's a problem related with Vimeo? Should I install some kind of plugin for Vimeo? Thx Antonio

You probably need to set the default audio device and close and restart Firefox to make Firefox use or switch to the selected audio device.

The PC was restarted many time the audio device is set to speakers. In youtube firefox audio works properly. In vimeo it doesn't.

Do both sites use the same plugin or possibly the built-in HTML5 media player with the video tag?

What I mean that the website might be using the built-in HTML5 media player and not the Flash plugin to play the media files. That can make a difference. The Flash player always gives its own context menu if you right-click in the player area.
