Hi Carkins,

You have probably already done this but the first thing that I'd try is to open the "Playback" settings (right-click on the speaker icon) and double-check that all the sliders are up full. (See image below.)



Note that the red symbol on the "Auxillary" speaker means that my auxillary channel is muted.

Your version of Windows may or may not have the following option, but it would also be worthwhile to right-click on the speaker icon, select "Volume mixer" (if XP has it) and check that all sliders are fully up and that none is muted.



Lastly, I have found that Reaper runs best with ASIO (I use ASIO4ALL).

Regards,
Noel
