Ever since a couple of days ago, I've been having driver problems. I have a realtek AC'97 that came with my motherboard and it has never failed me until now. Basically what happened was I tried to play an audio file and the message came up that the audio device could not be found, so I uninstalled the whole driver then re-installed it. At first Windows Media player played a song, but Now, I can hear all the normal windows sounds but i still get the same error message from the media player. Plus, it says I have no audio hardware plugged in but my drivers are all working properly. Any ideas?

What is the audio file extention?
Will it play in another audio player?
Have you installed anything related to audio recently?

A little more info would be helpful!

I am with Firefox... We need some more information. Computer name, OS, etc..
