I don’t know what happened. I did a normal update, and as far as I could see, there was no audio, video or any other media related update in the online that I carried out. After caf4926 helped me out the last time a couple of weeks ago, everything was running perfectly.
After this up date, though, the video on my usual sites, BBC, CNN, Youtube, and a couple of others, is fine, but there is no audio at all. However, when I download the videos from any of those sites and play them using vlc or one of the other players, the audio is there.
I don’t understand why the audio wouldn’t work in FF (v. 3.0.13), but works without a problem when I use Kaffeine, VLC, (SM/K/M)player, or any one of the other media players I have.
