The integrated audio works. AC'97 works. However, the problem is that "after" running applications like Garageband, iTunes, and Front Row, I don't hear anything from my audio. When I reset the audio channels through MIDI setup, I am not even able to adjust the volume. Its set at a particular default where I can't hear the volume going up or down. If there is a fix for this out, do let me know because it is just an issue between the interaction between the AC'97 driver and other applications. Is there an updated AC'97 floating around somewhere? The audio is running successfully, but when it comes to running audio applications, that's when things go upside down. I would appreciate everyone's help on this, because this could be an issue no one is aware off. Thanks a lot. Greatly appreciated. =)
