See What to do if Firefox won't play any sounds and Fix common audio and video issues

You can click the Volume icon on the Windows Taskbar near the clock and click the Mixer link at the bottom to open the mixer.
You can adjust the volume level for each application in that window, so make sure that Firefox is not muted or set at a low level.
You will only see the Firefox program in the Mixer if you are on a website that plays sound.
