I have similar problem.
Windows 7 x64, Java 8u192, jAReC_v3.0, IC-7610
When I enable audio in jarec it is closing itself when andtroid app is connecting with it.
In my phone i see "connected" than jarec on PC is closing itself.
No problem when "use audio" is disabled.
Any ideas how to get audio running?
