Summary
When using the Plugable UDS-7IN1 docking station with an iPad, some communication applications, including FaceTime, may not allow you to select a wired headset or microphone connected through the dock's 3.5 mm audio jack.
This happens because certain iPadOS applications have limitations in how they recognize or route audio through external USB audio devices. The issue is not specific to the UDS-7IN1 and has been observed with other docking stations.
If your headset or microphone is not working as expected during calls, using a Bluetooth headset or the iPad's built-in microphone may provide a workaround.
Applicable To
- Plugable UDS-7IN1 USB-C docking station
- Compatible USB-C iPads running iPadOS
- Wired headphones or headsets connected to the dock's 3.5 mm combination audio jack
- Communication applications that may restrict external audio input or output selection
Why Does This Happen?
The UDS-7IN1 includes a 3.5 mm combination audio jack designed to support compatible headphones, speakers, and headsets with microphones.
However, iPadOS and individual applications determine how audio input and output devices are recognized and selected.
Some communication applications may not recognize the dock's connected headset or microphone as an available audio device, even when the same headset works correctly with music, videos, or other applications.
For example, FaceTime may route audio through the iPad's built-in speakers or microphone instead of the wired headset connected to the UDS-7IN1.
This behavior does not necessarily indicate a hardware problem with the docking station.
Affected Applications
The following applications or features have been observed to experience audio routing limitations:
- FaceTime: May not allow the expected selection of a wired headset or microphone connected through the dock.
- Siri: May not recognize or use the external microphone as expected.
Other communication applications may behave differently depending on the application version and iPadOS configuration.
Important Note: Earlier documentation also identified Skype as an affected application. However, Microsoft retired the consumer version of Skype on May 5, 2025. Microsoft Teams and Zoom have not historically exhibited the same limitation in Plugable's testing, although audio device behavior may vary with application and iPadOS updates.
Recommended Workarounds
If your wired headset or microphone is not functioning as expected with a communication application, try the following:
- Use a Bluetooth headset: Connect a compatible Bluetooth headset directly to your iPad and select it as the audio device, if the application provides that option.
- Use the iPad's built-in microphone: If the external microphone is not recognized, disconnect the wired headset or adjust the application's audio settings to use the iPad's internal microphone.
- Check the available audio outputs: Open Control Center on your iPad and review the available audio output devices. Select the dock's USB audio device if it is available. Keep in mind that some communication applications may override this selection.
- Test another application: Try playing music or video through the connected headset to determine whether the issue is limited to a particular communication application.
If audio works in other applications but not in FaceTime, the issue is more likely related to application-specific audio routing behavior than the dock's audio hardware.

Important Notes
- Audio routing is controlled by iPadOS and individual applications. The UDS-7IN1 cannot override application-specific restrictions on audio input or output selection.
- The 3.5 mm audio jack supports compatible wired headsets. However, not all communication applications recognize external microphones connected through USB audio devices.
- Bluetooth headsets may provide an alternative. Connecting a Bluetooth headset directly to the iPad can help avoid the wired audio routing limitation.
- Application behavior may change. Available audio devices and routing options can vary depending on the iPadOS version and application updates.
