I have two machines one running windows 7 and one running windows 8.1. The windows 7 machine working fine but running on windows 8.1 for some reason the project audio will NOT play unless you click on sound mixer to display the wave form edit mode. The clip audio plays but the audio WILL NOT play in project mode. All video's are game video's or DMV aero desktop recording using fraps as the video recorder uncompressed I've even transfered files form my windows 7 machine that play fine in project mode to the windows 8.1 machine and the same issue, I've tried every file format and they are all the same. When I create a video file via share, the sound is fine and plays normally after creation in the preview window, but for some reason NO audio will play when previewing the video in project mode regardless of the file.
Running on Windows 8.1
VS Pro x4 14.3.0.5
Project template is default doesn't seem to matter, even if I change these settings video project sound will not play and is not muted. The compression and rendering is done at the end using Xvid MPEG-4 Codec, PCM, 48.000 kHz, 16 Bit, Stereo and audio plays fine.
NTSC drop frame (29.97 fps)
MPEG files
24 bits, 720 x 480, 29.97 fps

Video data rate: Variable (Max. 8000 kbps)

or

I could list all the video's I have tested this on but I don't think that is the issue. Here is one sample.
But due to the language barrier and the constant sales pressure being babbled at me I was not able to get my point across.
