ObservationWhen using wired headphones/headset and microphone with communication applications with iPadOS and the 3.5mm audio combination jack on the UDS-7IN1, a user may not be able to select their preferred audio output/input device. The issue resides with Apple's communication apps having a limitation with audio routing capabilities. This issue is not specific to the UDS-7IN1 and has been observed with other docking stations.   Affected communication applications FaceTime Skype (Siri is also known to be affected) **Please note that applications such as Microsoft Teams or Zoom do not appear to have this limitation. Workaround solutionWe recommend using a Bluetooth headset or onboard system microphone to circumvent this limitation.
