However, only one audio output can be selected at a time.

You can choose an audio output via the WiiM Home app or the built-in screen (if available).
Via the WiiM Home App
Navigate to the Devices tab > Device Settings > Audio Output in the WiiM Home app, then select an output.

Sub Out
Some WiiM devices (e.g., WiiM Amp, WiiM Amp Pro, WiiM Amp Ultra, and WiiM Ultra) support the Sub Out port, dedicated for connecting a powered subwoofer. The Sub Out port can be used together with a selected audio output except Bluetooth Out, Headphone Out, and DLNA Out.
