So I'm going Guitar>RP500>Reaper 4.

Today, I plugged in and came across this issue.

Im getting a high pitched squealing from amp when the USB cable is plugged into the RP, and when running Reaper, hitting Play or Record just causes it to freeze. No idea what is causing the problem. Reinstalling drivers for the RP didnt fix it.

I'm running Windows 8.1 x64 if that is of any help.

Any idea how to fix this?

EDIT: Switching from Reaper to WSAPI fixes the freezing but not the squealing, and there is a lot of latency.
