Problem Solution
No sound in HDMI ARC
mode
• Make sure the input source is set to HDMI ARC; the LED will display 'HD'.
• Make sure your TV or external device supports ARC function and connect the HDMI cable to the
ARC port of the TV or external device.
• In the TV or external device setting menu, turn on the ARC function and the CEC function.
• In the TV or external device setting menu, find the audio output settings and change the audio
output mode to 'PCM' mode (instead of Auto, RAW, etc.)
• Make sure both ends of the HDMI cable are fully plugged into the sockets.
• If your TV or external device is muted or no sound output, the LED will flash 'HD'; once audio
signal is available, the LED will display 'HD'.
• If none of these solutions work, try changing the HDMI cable.
No sound in Optical/
Coaxial mode
• Make sure the input source is set to the correct mode; the LED will display 'OPT' or 'COA'.
• Increase the volume of the soundbar to make sure it’s not muted.
• In the TV or external device settings menu, find the audio output settings and change the audio
output mode to 'PCM' mode (instead of Auto, RAW, etc.)
• For optical, make sure you remove the small caps on either end of the optical cable, and both
ends are fully plugged into the sockets.
• If your TV or external device is muted or no sound output, the LED will flash 'OPT' or 'COA'; once
audio signal is available, the LED will display 'OPT' or 'COA'.
• If none of these solutions work, try changing the optical or coaxial cable.
No sound in BT mode
