7. Troubleshooting

If you encounter issues with your Assistrust Sound Bar, refer to the table below for common problems and solutions.

Important Note for TV Audio Settings: For optimal compatibility, especially when using Optical or ARC connections, ensure your TV's digital audio output format is set to PCM or Stereo. Many TVs default to Bitstream (Dolby Digital/DTS), which may not be compatible with all soundbars, resulting in no sound.
