Is there somehting wrong with my comp.....

You have to set up your audio and midi inputs and outputs through Sonar and your soundcard. Start Sonar>Go to Options>Audio>choose playback and recording outputs. Go to Options>Midi Devices>choose inputs and outputs. Make sure your soundcard is not muted. Run Sonar`s Audio Profiler.
Hope this helps!

you should check your sound card , or input and output sound options ....of your sonar.
