Room Audio “Feedback”
If the audio from your room-mounted speakers seems to have a buzzing, hissing, or “feedback” sound, you may want to check the audio controller in your cabinet. In general, it is recommended to turn down the volume on the audio controller (such as the Computer and Aux dials) and/or turn up the volume on the source itself (such as the device the aux cord is plugged into, or the Clevertouch Board or computer that you are playing media on). This will tend to reduce the degree of noise.
