Troubleshoot No Audio on Alienware Monitors When Using HDMI ARC eARC Port

Affected Products:

• Alienware 32 4K QD OLED Gaming Monitor AW3225QF
• Alienware 27 4K Dual-Resolution Gaming Monitor AW2725QF

1. Ensure that the monitor firmware is updated to the latest version.
2. Use a High-Speed HDMI cable to connect the Alienware monitor to the soundbar.
   Note:

   • If the soundbar supports ARC only, an HDMI 2.0 or above cable is required.
   • If the soundbar supports eARC, an HDMI 2.1 cable is required.
   • Some soundbars come with an HDMI cable in the box. Ensure the HDMI cable meets the requirements stated above.
   • The HDMI cable that comes in the Alienware monitor box is a High-Speed HDMI 2.1 cable.
3. Some soundbars have more than one HDMI port. Ensure the HDMI cable is connected to the HDMI port that supports ARC/eARC.
   Note: Some soundbars do not have the words ARC/eARC printed next to the HDMI port. Check the documentation to identify the correct port.
4. Ensure the HDMI cable is connected to HDMI (eARC/ARC) port of the Alienware monitor (check the monitor documentation to identify the correct port).
5. Ensure that HDMI CEC is turned on in the OSD:
   • Open the OSD and go to Others > HDMI CEC.
