I downloaded the ASIO driver updater thing and enabled it in reaper, but when I do that I have no sound through my speakers.

Does anyone know how I could fix this?
you may need to go into the ASIO control panel and setup the driver so that it is using the correct inputs/outputs you want. i use ASIO4ALL and it is quite easy to do. never done it in reaper though, so im not sure how one would get to the control panel in that program.
