No sound in browsers or in youtube

I have sound in the speakers and headphones while using Itunes. There is no sound on any browser or youtube. i have updated the drivers for Realtek High Definition Audio. reboot, checked for driver update, no sound, disabled Realtek, reboot, enabled Realtek, reboot, no sound.

I installed the K-Lite Codec pack, reboot, nothing

Updated ATI Radeon Xpress 200 Series driver, reboot, nada

updated Marvell Yukon Ethernet Driver, not relevant really just thought I would pass that along

Reinstalled flashplayer

Acer computer cpu 3.06
2 gig ram
160 gig hd

windows xp
sp 3

Not sure what else I can do

would be really grateful for the help

Check volume controls in control panel/sounds and audio devices/speaker volume,check speaker volume on both left and right speakers is up,open device volume/advance to see they are all up and not muted with a flash video playing check the volume is turned up at the bottom right of the video.

In IE go to tools,internet options,advance and make sure enable sounds in web pages is ticked.

 

I checked everything and went to IE and checked and everything was ok, but still no sound.

Anything else I can try.

 

If FF means FireFox, I tried to find file types but couldnt see them in the options section anywhere. Was I in the right place?

Also I thought maybe if I simply restored the computer to a time before this problem that might work. However I tried twice and it would not restore. I tried two different days.

What next?

 

You said the problem didn't start till you upgraded your sound driver? I would suggest that you uninstall the Realtek sound driver and install the factory set driver that came with your computer or do a Rollback to the previous one.

 

I only upgraded the driver after i had the problem. I tried turning it back and it still didnt work. Anything else.

 

ok i have sound back again. out of desperation i went to the acer website and updated all the drivers that were available. i did not update the bios. this didnt help.

i finally updated the flash player.

whoo hoo the sound started working after that.

thanks for all your help.
