Hey devel.bmad, i am sorry i am no help to your problem however i am trying to implement voice chat on PC alone, but am finding it difficult to find info on for unreal engine 4. I thought that maybe you might have had it working for PC initially and then worked on getting it sorted for android, and if so, maybe you could give me some information on how you got voice chat on pc working (even just links to any help if you used any) , it would be much appreciated. Thanks a lot.
