Why do I hear Public Radio 90 instead of program audio on Public TV 13?
WNMU-TV provides a “second audio program” (known as SAP) during our broadcasts. On Channel 13.3, our SAP provides audio from Public Radio 90 broadcasts. If you are hearing this audio, your television is set to listen to the second audio program. To receive our regular TV13 audio, you need to go the audio setup menu on your TV or VCR and select “stereo” or “mono” instead of “SAP.” Some remote controls also have a button labeled SAP or Audio to control this feature.
