No sound on Firefox...with streaming video

I recently had major issues with my computer, which you guys helped me solve so a big THANK YOU for that.

SO my computer is running great now HOWEVER, when I try to watch a video on YouTube I can see the picture but there's no sound? I can listen to iTunes and Spotify fine but my very favourite website isn't working I'm devastated!

I've updated Firefox, I've downloaded the latest version of Adobe Flash player, I'm really at a loss now.

Any suggestions on how I can solve this problem? I'd be forever grateful!

Bumping cos I'm getting abit desperate here

Have you tried these:

Does the sound work when you stream video in any other browsers? Like Internet Explorer, Safari, or Opera. If it does, then the volumes and settings aren't the problem. A full uninstall and reinstall of Firefox may help.

Thank you both for the replies. Its weird I just used Safari and I was able to watch a video WITH sound using quicktime and flash. However when I went to YouTube still no joy?? Its a real pain as it'll probably be something damn simple.

So I've done the whole 'wavesweeper' registry thing and still no YouTube sound its really starting to make me mad. Anyone know any other avenues I could go down?

Do you have Firefox add-ons such as ADblock or NoScript enabled?

I'm not 100% sure what or where those are! So the honest answer is I dunno.

Both are extensions for Firefox.
ADBlock helps block ads of all kinds(including flash ones).
NoScrip blocks malicious scripts/content on websites.

Open Firefox, Go to Tools > Add-Ons.
What do you see under Extensions?

Also, try uninstalling Firefox and rebooting your system.
Then, install the latest version again and make sure you get the flash player plugin for Firefox.

Firefox 3.5.5
Flash Player Plugin

Let us know if it worked.

Still no joy after installation then reinstallation...the add ons I see are as follows..

AVG Safe Search
Java Quick Starter
Microsoft Net Framework Assistant
Move Media Player

The thing is Windows doesn't even have the little start up tune anymore either? Do you what I mean, yet Spotify, Itunes, Apple Quicktime all seem to be working. I'm really ready to get all *HULK SMASHY* on the damn thing!

Here's how you can get back the Windows startup sound:

Start > Settings > Control Panel > Sounds and Audio Devices > Sounds > Choose Start Windows under Program events > Choose Windows XP Startup under sounds >Apply and OK.

Back to the Firefox issue:

1. Verify that cookies are enabled in the Privacy panel in the Options > Preferences window. Verify that the site is not blocked in the Cookie Exceptions list.

2. You can allow the website as an exception in the Firefox pop-up blocker. The "Block pop-up windows" option is found in the Content panel in the Options > Preferences window.

3. Do you have the QuickTime plugin installed? If not, please do install it.

4. Make sure you follow this to uninstall and re-install the flash plugin. Uninstall flash plugin

5. Create a new profile in Firefox. Creating a new profile

6. If the above fails, try this Firefox - No sound

Let us know if the above worked.

Thanks so much for all your hints/tips. I tried all of the above and still nothing I really don't know what to do now.

Strange.
For others who were experiencing this problem, a reinstall of the flash plug-in did the trick.

Guess, you'll have to stick to other browsers to watch video streams online.

An OS reinstall wouldn't make sense at this point in time.

That's the thing YouTube isn't working on any of my other browsers? Its so strange. Thanks though.

FYI, There's a separate version of the Flash player for Internet Explorer.
Flash Player - Other Versions

And could you also give this a try:

If you can't hear sound within videos embedded on other websites or blogs, your computer may be blocking third-party Flash content. To correct this, follow the steps below:

1. Visit http://www.macromedia.com/support/document..._manager03.html.
2. The Adobe Flash Player Settings Manager should display.
3. Check the box labeled: "Allow third-party Flash content to store data on your computer."
4. To ensure the check sticks please click one of the tabs at the top of that box and then click back to the (Global Storage Settings Panel). The box should still be checked.
5. Once this is complete, close all browser windows and try playing an embedded video.

Please be advised that this action stores a Flash cookie on your computer. Flash enables this by default upon install.

If this step doesn't help, please check your Antivirus and Firewall software to see if you're blocking third-party Flash content.
