My current system is a Dell XPS 400. After installing an old-school rpg that uses pc beep sound, my real audio isn't working. I have a random audio codecs, SB F-xi, IDT High Definition sound codecs(which cannot start under a code 10), Legacy audio drivers, and a Unimodem half-duplex audio device, all showing for audio hardware. I have uninstalled and re-installed drivers, selected the proper sound device, nothing seems to be working, and I'm looking for a little guidance. Any help would be appreciated. Thank you for your time.
