I have a video in YouTube which lost its audio. When I uploaded it the audio was identified as 3rd party owned. I confirmed that I use 3rd party content in the video and that was all. However now the audio in the video is missing. But another one of my videos which has the same case doesn't have any problems with the included audio.
Both of my videos in question are tagged, categorized and unlisted. I just share the links to friends from time to time.
The mute video is quite long more then 30 minutes.
Did anyone had a similar problem and does the missing audio has anything to do with the 3rd party ownership of the content, which is my suspicion.
I tried to pose this question in the Google group for YouTube support but I was not able to create new topics there.
Thanks in advance for the answers.
