How do I make the sound louder on YouTube????

How do I make the sound louder on YouTube????

My speaker phone volume is fine, but when I play videos on youtube and window media the sound isn't very loud. I have downloaded phmregedit.cab but none of the changes I have made have made a difference so I reset them to the original settings. I would appreciate any help (P.S. I'm a noob)

thanks

hold in the scroll wheel and scroll up

Are you sure, Scott???

Are you using skyfire to view it?

still not loud enough, how do you use skyfire to view? I downloaded the phmregedit.cab to my cell I have tried making changes, is there anything i need to do after i select "done" so it will save the changes?

nvm thanks it worked
