Its been a reoccurring problem of late, every time I go on YouTube and attempt to watch a video, I am unable to hear the audio component.
However It does not appear to be a hardware issue, since when I play songs off media player or watch movies I can hear the sound perfectly fine.

I thought it might be an issue with flash player so I reinstalled it to no avail, attempted to update sound card drivers but it said I was already up to date.

I am not sure what the problem exactly is, If anyone knows how to fix it or has had a similar experience I would appreciate some feedback.

I use Firefox, and my Computer is an LG R405 Series with Intel Duo Core T5750 @ 2.00GHz, 4Gb of RAM, and I am currently running Windows Vista Home Premium.

Interestingly, when I boot into Windows 7, I don't have this problem so it appears to be limited to Vista.

Stupid question, but you never know : did you fiddle with the sound mixer (just left of the windows clock) ?

 

Another stupid question, but are you trying to watch videos with certain songs?because Youtube itself blocks audio from videos that fail to get permission to use a company's audio - it'll indicate as such in a small box under the video as it plays.

 

No I tried specific videos then any random video to see if it was just tied to a specific set of videos but it appears to be all videos on youtube. I also didn't fiddle with the sound mixer.

 

Funny, I just got my computer back from the shop and I have no sound.

 

Another stupid question, are you sure that the flash player audio volume is not 0?

 

I just experianced the same problem, no audio on videos on youtube. But then I tried the same link in IE, I usually use Firefox, and it worked fine.

Methinks its something to do with Firefox.

 

Or Chrome. It's pretty decent now.

 

hey im having the same problem as you sushiZ and i run Windows XP service pack 2 and this just happened recently so it is not limited to Vista

 

Just youtube right? Try another browser, or run firefox in safemode with no addons. If all else fails uninstall flash player with uninstall tool, registry and all, clear your firefox cache/memory and then install the latest flash.
