I have been trying to install sound on a WIN98SE system with a Shuttle AS45GT motherboard. After installing either the built in Avance AC97 or a PCI MAD DOG MM Predator 5.1 [only one at a time - I disable the built in on before trying the Mad Dog] the preferred playback and record settings are greyed out in the Audio tab of the Multimedia Aplet with "no playback device" showing in the selection block. Both cards do show up as appropriate under Multimedia/Devices. Both are also shown as functional Sound devices under the System Aplet. I have installed, uninstalled repeatedly using both the Uninstall feature of Windows and through Norton Smart Sweep, both in Safe mode and standard mode. Drivers for both are the latest from the appropriate Manu's site. Help! this is driving me crazy. BTW I also reinstalled Windows and updated the install.
