Audio doesn't work with flash based videos

[Zolty]

Flight sim gives me audio as does Itunes ect.
I have tried uninstalling flash and reinstalling (off the web site)
I have tried chrome, FF, and IE none work

Running Windows XP SP2, just put the computer back together not sure when it stopped working.

Any ideas?

I should mention I have googled the problem but all I can find are people telling me to do what I have already done.

I fixed the problem by reinstalling the OS. Fun stuff.
