Additional Information on HDMI ARC
When connecting your TV to your WiiM Amp or WiiM Amp Pro via an HDMI cable, ensure you use the HDMI ARC port on your TV or Blu-ray player. Other HDMI ports won’t transmit sound to the WiiM devices.
If you experience no sound, ensure that the HDMI ARC output on your TV is activated.
If there are control issues between your TV and your WiiM Amp or WiiM Amp Pro, verify that HDMI-CEC control is enabled on your TV.
If your TV lacks an HDMI ARC port, connect the Optical Out port of your TV to the Optical In port of your WiiM Amp or WiiM Amp Pro.
