OS in my Laptop is Vista, I could hear the sound before, but now it is mute, meanwhile other browser chrome support the sound and I play video in Media player, that means there is no problem with hardware

See:

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.
Current Firefox versions use the plugin-container process to run plugins, so you need to check the volume setting for the plugin-container process.
You will only see the Firefox program or the Plugin Container in the Mixer if you are on a website that plays sound.
