Hi. I know a good amount about computers but i have almost no knowledge about audio cards. I'm currently running a Dell Inspiron 1501 and have full factory default hardware and settings (its a dell, many personal problems with dell so i don't mess with them anymore). One day my volume controls "disappeared" so i rebooted my comp and they still weren't there so i uninstalled my audio driver and rebooted then reinstalled the driver with another reboot. Nothing. So i repeated this process 6 times, 3 installing from the CD provided by Dell and 3 times from dell.com. Still nothing. I then decided to do an operating system repair. Took over 24 hours and got to the Windows XP Boot screen (the one with the XP symbol right in the center durring pc boot up) and it said "Please Wait...". Sat like that for 24 hours. So I turned off my comp and rebooted it. Everything works but the audio still. After the "repair" i tried twice from the CD and twice from dell.com and still nothing. I don't know if its my sound card or just faulty downloads? Please help!
