Audio does not play in videos in SSP(TS089)
Videos will play correctly within SSP, but the audio portion does not play.
The audio in the file does not comply with the supported video combinations.
Refer to KB MI018 for additional details.
The audio in the file was not encoded in stereo. Monaural audio does not currently work during video playback for H.264 files. The root cause of this is not known at this time but is under investigation.
As a workaround either obtain or encode your H.264 videos with stereo audio. If you do not create your videos, check with your content provider to get files with the correct encoding.
NOTE: This issue was resolved in the October 2010 Release.
