Game level Complete !

More searching for the issues surrounding the maximum amount of channels that could be used resulted in little findings so after speaking with my supervisor I looked into the voice limiting option within UDK. I went through each of the sound cues which were created and edited the properties to define the maximum amount of instances of each cue could play at any one time. This was a last effort to try and get the level working outside of the editor.

Voice limiting option (Max Concurrent Play Count) was somehow overlooked earlier in the project phase

Before trying again to package the game I got a response from one of my posts on the Epic Games forum which shed some light on the problem. basically I had changed the max channels code for the editor only which would not transfer over to my packaged game. The following code was added to the BaseEngine.ini and BaseGame.ini files to change the max channels available in the exported game.

BaseEngine.ini which was edited to increase the maximum amount of audio channels available to the game

BaseGame.ini file which was edited to increase the maximum amount of concurrent heard sounds (by the player) 

The level has now been tested on a separate machine and appears to be functioning well, now time for testing
