How to check whether SAP/MTS is enabled

Secondary Audio Programming (SAP) is a service carried alongside a TV channel that is used to broadcast for language or accessibility such as:

  • An alternative audio track for the program in a different language, or
  • Voiceprint, an audio service of particular interest to vision impaired, learning disabled, mobility-impaired and those in need of enhanced literacy skills learning English as a second language

 
To disable SAP on your TV:

  1. Locate the original remote that came with your Television (not the Shaw Remote)
  2. Press the MENU button and locate the AUDIO option
  3. Press the SAP, AUDIO or MTS button on your remote
  4. Ensure that you select either MONO or STEREO, instead of SAP or MTS

 
Please note: the steps above may differ depending on the manufacturer of your TV. Please refer to the documentation provided by the TV manufacturer. If you are unable to change this setting with your remote control or are unable to locate the SAP, AUDIO or MTS button, attempt to use your TV’s on-screen menu to locate the audio settings. Common labels for the TV audio menus are labelled: SAP, AUDIO SELECT, B-AUDIO, MTS, or MENU.
 
To disable SAP on your Digital Box:

  1. Press the MENU or SETTINGS button twice on your Shaw Remote for a full-screen Menu
  2. Scroll down the Menu until Setup is highlighted and press OK
  3. Select Audio Setup and press OK
  4. Ensure that the Default Audio Track is set to Channel default
