How come I can't hear audio from iPad when connecting to iConnectMIDI4+?

When connecting the iConnectMIDI4+ to my iPad, I can't hear the audio through the iPad speakers or headphone jack.

By default when connecting an iOS device to the iConnectMIDI4+, the iOS device's sound it passed to the iConnectMIDI4+ which disables that iOS device's internal speakers and headphone jack.

To change this, open the iConfig application, and under the Audio Info section, de-select "iOS " for the iCM4 USB Device Jack and then perform a "Commit & Reset".
