Well, you know what they say about the best made plans: DELL seems to have a proprieatry design of its case and there is no way any MOB with a configuartion different than that of a DELL MOB can fit into the case (At least for the Dimensiion E520). So, if HOOV or anyone else is up to troubleshooting the lack of audio, I am willing to try anything to save my Mom from having to purchase a new system. The Creative Labs SB0790 PCI Sound Blaster X-Fi Xtreme is installed; I confirmed that integrated audio is OFF in BIOS; there are no remanants of Siigmatel Audio drivers or software on the system; I went to the Creative Labs Website and made sure the drivers for Vista-32bit were installed for the Creative Labs SB0790 PCI Sound Blaster X-Fi Xtreme. Device Manager is clean; I wanted to see if I needed to force an additional hardware installation by foing into Add New Hardware, but for Sound, Video and Game Controllers, Creative Technology Ltd. as a listed Manufacturer only lists Unsupported Game Port for Creative
under Model: there is no PCI Soundblaster card listed. I did not install this as I read too many threads which state that the game controller is not supported in VISTA unless it is via USB, not via PCI. Lastly, I now have a hiss coming from both speakers, which gets louder as the volume control is increased. If I right-click on the speaker icon in the system tray, Windows Sounds do not work either when I select Test. I selected Default for the Creative Audio Control Panel, and I went into Services in Control Panel and made sure Windows Audio and all Audio for Creative is Started. To play safe, I restarted all audio services, rebooted, and just have the hiss from the speakers. Anything else to try??
