Firefox audio codec support

Found out that there is no support for flac, vorbis and other codecs.

All recommendations have been implemented

Also installed ffmpeg and ffmpeg-libs from RPMFusion.
Also installed mesa-vdpau-drivers-freeworld and mesa-va-drivers-freeworld

I think I saw your post on Reddit as well. What I did was install ffmpeg-free from rpmfusion-free. I know you commented there that you did that as well. I can’t remember what type of video card you have, but I have an Intel card and had to do the following:

Hardware Accelerated Codec


Using the rpmfusion-nonfree section

sudo dnf install intel-media-driver

or Intel(older)

Using the rpmfusion-free section

sudo dnf install libva-intel-driver

Hope this helps!

Thank you all and I apologize, it’s not the codecs, it’s the firefox configuration. After resetting the settings to default everything is ok.
