Audio cuts off when recording BF3 on PC

[Neon1012]

First off If I'm posting in the wrong section I'm sorry I'm new.

I recently started trying to record game-play on BF3 and I'm having serious problems. When I start recording the sound stutters and then cuts off completely. Then I'm unable to stop recording or exit the game without the game crashing and corrupting the recorded file (this happens with every program I use to record; Fraps, Dxtory, Cam Studio, BDcam etc.). I have recorded on other games and although I get some sound stuttering it records fine.

I can run BF3 on full settings at over 150fps so I'm pretty sure its not my system specs but here they are anyways.
