Issues with the AUX/Audio PortUpdated 8 months ago

If you're experiencing problems with the AUX/audio port on your adapter, follow these steps:

1. Manual Audio Output Selection:
   
   
   • You need to manually change the output device on your MacBook.
   • Go to System Settings > Sound > Output (or System Preferences > Sound > Output on older macOS versions).
     
     
2. Selecting the Correct Output:
   
   
   • If no monitor is connected via HDMI, look for the name of your adapter or "USB Audio Device" in the list of output devices.
   • If a monitor is connected via HDMI to the same adapter:
     • The output device may display as the name of the monitor instead of the adapter.
     • Select the name or model of your monitor from the list.
       
       
3. For Setups with Multiple Monitors:
   
   
   • If you have two monitors connected, you may need to test each one:
     i. Select the first monitor name in the output list.
     ii. Play a test sound.
     iii. If you don't hear audio, select the second monitor and test again.
   • The monitor name that produces sound is the one connected to the 9-in-1 adapter with the AUX output.
     
     
4. Testing the Audio:
   
   
   • After selecting an output, play a sound (e.g., music or a system sound) to verify it's working.
     
     
5. Troubleshooting:
   
   
   • If you don't see your adapter or monitor listed, try unplugging and reconnecting the adapter.
   • Ensure your adapter's firmware is up to date.
   • Check that the AUX cable is securely connected to both the adapter and your audio device.
     
     
6. Volume Control:
   
   
   • Remember to check both the MacBook's volume and the volume of the connected audio device.
