Our game made in Unreal Engine 4 is now released but there is no audio on Xbox one, we have a mp4 splash screen which has sound and does work, but there is no audio for the rest of the game, despite it working perfectly fine in Xbox Series. We’ve been looking for possible causes but can’t seem to find a solution. Could it be a setting we’re missing? Or is there a plugin missing probably or something like that? Any suggestions would be apprecciated.
I found this other post that pointed to the solution, the XboxOneGDKEngine.ini has a default AudioSampleRate value of 0, which makes the game silent. Changing the value (we did to 48000 as the post suggested) and it solved our issue.
