Video No Sound on YouTube, MySpace and Flash Video on Mac OS X
When watching web pages with embedded Flash video or animation such as movie or video clip on YouTube and MySpace using Mac OS X, users may hear no sound. The no sound audio output problem happens despite video playback is fine, and the issue can happen on any web browser, i.e. Safari and Mozilla Firefox. Strange thing is that, when using other applications such as RealPlayer, QuickTime Player and VLC Player, the sound is played properly. And no audio output issue does not affect embedded QuickTime including HD contents on the web.
Apple Mac OS X support site explains that the no audio from certain multimedia content issue is caused by some audio applications that change the computer’s audio settings to a sample rate that is too high for other applications to use. The notorious programs include certain versions of Real Player, VLC Player and Audacity.
The solution to solve the Internet movie no sound or audio output is to reset the audio setting in Mac OS X to original configuration:
- Open “Audio MIDI Setup” (/Applications/Utilities/), then check the “Audio Output” setting.
- Change the “Audio Output” setting to 44100.0 Hz.
- Quit Audio MIDI Setup.
If the Audio Output setting is grayed out or disabled, go to “Properties For” tab in Audio MIDI Setup, and select “Built in Output”.

Flash No Sound WaveMapper Solution
Launch Registry Editor by typing regedit at Run command.
Navigate to the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Drivers32
On the right pane, and check for existance of “wavemapper” registry subkey, the mail culprit causing Flash no sound. If not found, create a new String value named “wavemapper”, and give the entry value “msacm32.drv”.
If wavemapper entry is already existed, ensure that its value data is “msacm32.drv”.

I was able to hear video on Youtube until yesterday. I checked all the MIDI settings and they are all as you suggested. Still no audio.
Any other suggestions?
Thanks.

I tried all the tricks but still they didn’t solve the problem, until I saw someone talked about installing CCleaner to clean some cached files … So I installed CCleaner, and cleared all the files selected by default there, Boom! It worked! Youtube suddenly has sound!

Hi i have the same issue ..
I am trying to follow “Start -> control panel-> Sound,speech audio devices -> Sound Manager-> digial audio – set to 44.1Khz”
but I don’t find ‘Sound Manager’ under or ‘digital audio’ .. I checked this several times .. either this is not really present in my comp or I am looking at the wrong place.. Can someone give me a clue

THANK YOU THANK YOU THANK YOU !!!
the ‘audio output’ change solved my web sound problem!
i’ve been looking for a simple answer like this for days now, and finally found it here. short, clear and to the point.
a clue for other users: the application that must have changed my audio settings was a modular synthesizer demo version. it happened without any prior notice.

I had the similar issue where there was no sound when i use flash on the internet (both firefox and IE). But the computer sounds worked fine. Tried upgrading the IE and uninstalled and reinstalled flash. Nothing worked. Then read your forum.
Solution: In windows XP, change the sound settings to 44.1KHZ. Start -> control panel-> Sound,speech audio devices -> Sound Manager-> digial audio – set to 44.1Khz.
That worked. Thank you guys, by changing the setting to 44.1KH on windows got it working.

La solución está en tus narices, es el control de volumen de la ventana de video, esta en mínimo, por más que subs el volumen de tu PC no vas a escuchar nada.
He visto ya varias veces que las personas no ven ese control.
