How To Fix The No Sound Issue in Firefox Flash

You can see alot of posts on adobe flash player forum like

Anything like YouTube, MySpace, that uses Flash to play sound is giving me nothing but sound works for everything else. Uninstalling and reinstalling doesn’t work. Installing an older version doesn’t work. This only started happening in the past week or so, and as far as I know nothing changed. Googling just gives me a bunch of people having the same problem but on Linux, so not much help there.

or like

my pc don’t have audio only when i try to watch any website like youtube or any other music video i use to watch it but for some reason is not working,the weird think is that i i could play music or any video and i have sound, is only in the web, all my sound drivers are ok

Finally I found proper easy fix for Adobe Flash Player 9 missing sound issue for Windows XP – fixing some sound-related registry setting (wavemapper to be certain) simply worked.

Good idea is to scan your system with good Antispyware / antivirus software and fix system errors with this tool, as it will save you from many annoying problems.

Next, you can download my precompiled registry fix – zipped REG file for Windows. File listing:

Windows Registry Editor Version 5.00<br /><br />[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32]<br />“wavemapper”=”msacm32.drv”<br />

If you paranoid about downloads you can fix it manually, here’s how:
start regedt32 (Win+R, type “regedt32″), go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32 location and make sure you have wavemapper with value msacm32.drv

It looks like ffdshow codec causing trouble, remapping all audio codecs to itself.
Now hear youtube!

  1. The link that you gave us (for that so-called anti spyware software) is really a bad joke.
    You could try to advertise a REAL anti spyware program, not a w.p.o.s. like that

  2. I have just install linux mint 4.0 on my laptop Acer travelMate 6291. But I cannot get any sound output. Itried everything, even reinstalling
    does anyone has solution to this?
