I would suggest you to reinstall your audio driver even though device manager doesnt show warnings.

Hi, how would I go about doing that?

My audio doesn't work on youtube videos

uninstall all versions of flash player you can find in the add /remove programs section in your control panel...
then go here and go thru the flash troubleshooter

I will do this as soon as I've finished making this reply.

Try this:

How To Fix:

• Go to START-->RUN and type regedit to open the Registry Editor
• Navigate to the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32
• Now right-click on the heading Drivers32 and select NEW-->STRING VALUE.
• Call this new String Value wavemapper.
• Now double-click the wavemapper entry you just created and for the VALUE field, type in msacm32.drv and click OK.
• Close the Registry Editor and try watching a video on youtube again.

I saw this fix before when I was browsing for an answer weeks ago on another website.
I already tried this and the same thing happened as last time.
I go to drivers 32 and make a new string value called wavemapper and it says:
"The registry editor cannot rename new value #1. The specified value name already exists. Type another name and try again."

In other words, wavemapper and msacm32.drv already are present, they haven't been deleted. I can see them right now.
Here's a screenshot:

Hey,

@happyrock:
Uninstalling all my versions of flash and using the troubleshooter didn't work.

@Mac
1. I think the latest version is installed.

I've got version 11,4,402,265 installed and the version that the bug refers to is, i think, version 11.3.300.257.

Just one comment, i've checked on my flash player settings it says:
"ActiveX Version: 11.4.402.265
Plug-in Version: Not installed"

I'm wondering if the not installed plug-in may be the problem? If so how can I change that and install the plug-in version please?

2.I've checked my chrome. I went on chrome and selected the toolbar and then "about google chrome" it said this:




seems to suggest that everything is updated.

3. tried html5, didn't work.

Thanks for your patience with me guys.

• Type "about:plugins" (without the quotation marks) into the address bar at the top of a Chrome browser window.
• Click "Details" at the upper-right corner of the page.
• Find the "Flash" (or "Shockwave Flash") listing on the Plug-ins page and click the corresponding "Enable" button.
• Close all Chrome windows and restart the browser.

and try again

Both of them are already enabled, neither have been disabled.

Press Windows+R key and type

devmgmt.msc and click ok

Expand Sound,video and audio controllers

Right click on it and uninstall your audio driver

Restart the PC and it should automatically reinstall on bootup

See if that works.
