Hmmm this is weird...

No sound for internet videos. I googled it and people suggested plugging the jack into the correct slot, but it was working a day ago. Already checked and my soundcard is set as the audio device. Any ideas? Oh, Im using Firefox.

thanks

--edit--

Never mind, simple restart fixed it.

Glad you got it fixed, flash player reinstall might have been my recommendation for a solution but oh well.
