Im not sure what revision this was in but I know it was shortly after 0.99 r4287 because it's been going on for about at least a month that when recording a video then when I stop the recording to play it back the Audio from the game isnt there and it's just nothing but the video. I just recorded this small sample and uploaded it as unlisted to report this bug. Using the same settings the recorded audio did work in the video before the 0.99 r4300 began so im not sure what they did that caused the audio in the recorded video to disappear but hopefully I can get this alerted to them.
