No Audio on Local Channels
If you have audio on most channels, but have silence on some or all of your local network channels, you may have the Secondary Audio Programming (SAP) turned ON.
To Turn OFF the SAP on your cable box:
- Press the Settings button on the digital remote. Result: The Quick Settings screen displays.
- Highlight either Disable SAP or Choose SAP Language (only one of these options will display on your screen) using the Up or Down arrow buttons.
If Then Disable SAP displays Press the Select button. Choose SAP Language displays Use the left or right arrow buttons to choose the English setting and press Select.
- Your audio should return.
If the above quick fix doesn't work, there may be a problem with MTS, Stereo or another SAP issue. Try the following:
- Verify in the program listing guide that the program has MTS, Stereo or SAP features.
- Check to see if the MTS, STEREO or SAP light on the TV or VCR is on.
If the light is not on, push the "MTS", "STEREO" or "SAP" button on the TV or VCR.
- Adjust the fine tuning on the TV set to restore the stereo or SAP.
Low Audio Level on Premium Channels
If you are experiencing decreased audio on some premium channels, or you are having difficulty hearing the dialogue, however the background sounds come through clearly, the "Audio: Range" is out of adjustment.
- To correct this, follow these steps:
- Press the SETTINGS button twice.
- Locate Audio: Range in the menu.
If... Then... You would like the best audio quality. Choose the Narrow option. You have a stereo audio system connected. Choose Normal or Wide.
Not all programs are compatible with the Wide setting, so the volume may appear to be washed out or too low to hear without turning the volume up extremely high.
Poor Audio Quality
Try the following fixes for issues with poor audio quality:
- Check the Music Choice or DMX digital light indicator:
- If it blinks, check all connections from the wall to the MC or DMX converter.
- If the light is solid, check all audio connections from the MC or DMX converter, through the stereo and out to the speakers.
- Check to see if there are worn selector switches, volume knobs, or tone controls as these can cause poor audio quality.
If the audio problem persists after taking these steps, contact your Cox cable customer service representative for assistance.
Static/Buzzing in Audio
If you hear a static type sound, or buzzing in the audio while you watch a program, the audio settings between your TV and the cable box may not be set within the optimal quality range. You can correct these settings by doing the following:
- Using the volume control buttons on the TV, turn the volume all the way down to 0.
- Using the volume controls on the cable box, turn up the volume until it is at it's maximum.
- Using the TV's volume controls again; raise the volume to a comfortable level.
