When I watch a Youtube video in Firefox, there is no sound. The same video has sound if I watch it in Chrome. Also, other types of videos have sound in Firefox. This started happening a few weeks ago. Until then the sound worked fine.

I have Windows 7 and Firefox 23.0.1.

Thank you all for you efforts. None of the suggestions solved the problem. However, the sound has started playing again on its own. I don't know why it stopped working & I don't know why it resumed working. But it is working now. Thanks again.
