  If the Adastra Desktop's power LED is on but there's no sound from external inputs, first, verify that the connecting cables are properly connected and in good working order. Next, check the volume and power switch on the external microphone or line source. Ensure that neither the main volume nor the microphone volume control is turned all the way down. Lastly, if you're in AUX mode, press the Play/Pause button to ensure the input isn't muted.
