Hi @SansCowz! Can you be a little more specific?? It might help other members to know exactly what you did to fix your sound problems.
Did you get a driver from the Biostar site?? Was it for W7?
Hi! @Joseph Gargery . Welcome to the forum! Nice screen shots and good information for installing a driver from devise manager!
That procedure works well, but will install the latest windows drivers and that may not be the best and most recent driver.
The best place to get drivers is from the manufacture of your PC or from the Mother Board!
PS I don't think the OP has said for sure how their issue was solved. From their reply, it would seem that that they probably down loaded the driver from Biostar. OP had said that installing from devise manager didn't work for them. I'm of course assuming this. The OP however said that Biostar fixed it. It's all good that the issue has been solved and the team effort worked again.
