I just added a sound blast Sb0090 to my desktop, due to issues with sleep mode that the onboard sound was having, mainly driver not working when coming out of sleep mode. Now I am having a ackward problem, This card worked very well in a older machine and now I have downloaded the vista driver and I get a strange buzzing noise i guess in the background of whatever I am doing, I did install the latest driver and this issue doesn't seem to stop, is there anything i can try or do? This really is a good card and i'd hate to have to buy another one just to get it to work with vista. thanks in advance.
