Verbatim 8-in-1 USB C Hub w/Dongle for Laptop - 100W PD, 2 USB 3.0 Ports, 2 USB-C Ports, SD Card Readers, HDMI, 3.5mm Audio

Here's an example of one with headset: https://www.amazon.com/dp/B08FBMQKRP and here's one without: https://www.amazon.com/dp/B0D1XLNWP2 The problems happen when the iPad has to choose between the headphone out and the audio interface (if you connect one). I think it gets confused and you have to choose the correct output and sometimes the iPad doesn't make a sound etc... So if you use an audio interface, just use the dock without headphone out.
