Reinstalled XP - No audio

[Sean138]

Hi, I've been lurking on here trying to sort myself out without having to create a new topic but I can't.

I recently reinstalled XP service pack 2 and there has been no sound since. After checking in device manager I get a yellow exclamation mark next to 'multimedia audio controller', also in the control panel under sounds and audio devices I am told there is no audio device.

The default audio device is Modem #0 Line playback.

I have used Belarc to get my system information and that is;
