I am using the onboard sound of this abit mobo together with win98se. I can't get 5.1 sound.... the centre speaker doesn't work if I set it to 6 speakers on Powerdvd5. I wonder if win98se supports 5.1 surround sound. I have the latest Vinyl AC3 driver installed to no avail. If there anyone out there who can help me with this prob? Thanks.
