whenever i try to play my realplayer, rioport audio manager, or anything requiring the soundcard, i'm given an error message. this never happened before the installation of my magicwriter cdrw 16x10x40 so i'm wondering if there's a connection. i've gotten the message that my soundcard could not be initialized. i've tried to fix the audio by going to Settings- Control Panel- Multimedia-Audio tab, but nothing allows me to change the information under the audio tab. i cant check off any boxes or click on playback devices. everything's just grayed out in color. can someone please help me???? i dont know too much about computers. thanks in advance.
