If you plug headphones or speakers into the 3.5mm port and get no sound, your device may not have switched its audio output to the hub. Try this:

1. Connect the Mobile XR Hub with Audio to your iPhone or iPad.
2. Plug your 3.5mm headphones or speakers into the hub's 3.5mm port.
3. Open Control Center by swiping down from the top-right corner of the screen.
4. Press and hold the audio card, then select the hub as the output device. It usually appears as "USB PnP Audio Device" or "General USB Audio Device."

The 3.5mm port works with most wired headphones, speakers, and microphones. If you still have no audio after selecting the hub as the output, contact us at support@satechi.com.
