.wav file not working

Hi there, I’ve listened to imported music & sounds from .wav files in Unity before, and now none of them make a sound, in neither the inspector nor game mode. I tried re-importing them, but with no further success. Does Unity 4 require a different file format or something? Thanks for your help.

I’m using unity4 (downloaded one week ago) and I’ve no problems with wav and ogg. I think is your computer problem…
Try to open file from windows media player (or other audio programs) for check if it’s an audio driver problem.

Check if you are in this same situation:
