No audio when plugging headphones on Android devices

Question

Hi, we have had audio issue for a little while now on our live application on Android. On most Android devices, when we plug in headphones when the application is active, there is no more audio until the application is put in background and brought back in focus.
We think either the audio thread gets suspended/killed or that Wwise somehow loses connection to the device. (note that the issue only happens if the headphones are connected once the application has started running)

We've recently upgrated our Wwise version to 2019.1.7 in the hopes that the issue was fixed but it is still happening.

Any help is appreciated
