when I open any website like youtube.com any play a video I cant hear the audio, this happen to me in more than one website. When I open an audio file from My Documents it plays just fine same with when I play a CD or DVD, its just that when im browsing the internet I cant hear the audio! also the volume control has disapeard from my bottom right corner of the screen! This has happend just recently when I got an automatic disk clean up message because I had little space left on my hard drive. I did the clean up thing, what it did is zipped some file or something, anyway I dont know if this is what causing the problem because Im getting this audio problem just after I did the disk clean up. Do I need to reinstalling my C-media audio device or something? Any help would be apreciated, and thanks for your reply!
