Many of our players are having issues when looking straight up with sounds becoming erratic or stopping.

Is there a possible gimmble lock issue or divide by zero issue with the up case in the 3d api?

We are using studio 1.08.

Thanks  
Dale

There should be no issue if the vectors are set up correctly.

Make sure that the 2 orientation vectors for the listener are both perpendicular to each other and unit length (1.0).

If you can demonstrate some settings that give you a problem, ie values for vectors, please paste them here and we can test them for you.
