  2. Choose the device or group where you want the audio to play.
  3. Go to the 'Browse' tab, scroll down, and select the appropriate input option: HDMI ARC, Line-In, or SPDIF-In.

Supported Audio Format for HDMI ARC and Optical Input:

The HDMI ARC and optical input port on the WiiM Amp are tailored for stereo PCM audio. It does not support other TV audio formats like Dolby Digital, Dolby Atmos, or DTS.

To ensure compatibility and proper sound output, select PCM as the audio format on your TV or Blu-ray player settings.

Important notes on HDMI port:To connect your TV to the WiiM Amp using an HDMI cable, please select HDMI port on your TV or BD player marked as ‘HDMI ARC’. Please note that connecting to other HDMI ports will not transmit sound to the WiiM Amp.

If your TV doesn’t have an HDMI ARC port, you'll need connect to your TV’s optical digital OUT port with the optical input port of the WiiM Amp.
