I am trying to use my guitar with my Digitech RP360XP Multi-Effect Pedal. I can hear it through windows. The recording device is working, and I can actually hear it when I am in jammr with audio playback turned on. I can only hear it though. No one else can hear it for some reason.

Have you made sure that SEND is highlighted at the bottom of the Jammr window.

I have. No luck. I even try my regular headset microphone and I can hear myself through it but others cant.

Try right click on the speaker icon from the system tray (windows activity bar, down, right). Sample rate and bit depth must be the same in all settings, jammr app, speakers and recording windows. Look at properties/advanced tabs for changes if necesarily… I use 48.000/16.
