Hello! I am in need of some help with my audio configuration. I was going through my Add/Remove programs and uninstalled Java and Quicktime (trying to make space because my computer was so slow!). Unfortunately, now whenever I try to play a video on Youtube or listen to iTunes, I don't get any sound. An error message comes up saying "There is a problem with your audio configuration. Audio/video playback may not operate properly." I then went into Control Panel > System > System Properties > Hardware > Device Manager and found a yellow '!' next to 'Multimedia Audio Controller' (in 'Other Devices'). The only option available was to reinstall the driver but this message appears: "The hardware was not installed because the wizard cannot find the necessary software." I went to Dell.com and looked for drivers for my model (service tag: JFQC441) and found no results. I also tried putting the Devices CD-ROM from Dell into the Tower but no luck. I know nothing about PC's but I have a Macbook and have never dealt with anything like this before... And I want to avoid contacting Dell or the Geek Squad. If anyone has any suggestions please let me know. Thank you!!!
