I am using the onboard sound of an Abit KV7 motherboard and win98se. The prob is I am not getting true 5.1 sound. Is it bcos win98se does not support 5.1 sound as there is only an option for surround sound and not 5.1? Is there a way of resolving this prob? I am using PowerDVD5 and when I set it to 6 speakers there is no sound from the centre speaker and no dialogue/speech. When I set it to 4 speakers, there is sound from the centre speaker but it's not true 5.1. Thanks.
