The AudioLoopBackSample app in github has been updated to fix this issue https://github.com/blackberry/Core-Native-Community-Samples/tree/master/AudioLoopBackSample
This sample is updated to Disable MMAP on play and record Use type VIDEO_CHAT as opposed to VOICE (recommended by RIM audio team) Free up audio_manager handles properly (RIM audio team code review) Set the play to headset because VIDEO_CHAT defaults to speaker (recommended RIM audio team) Removed the conditional compile for the old SDK version as nothing that’s not built with the current SDK will run on BB10
