If you hear audio in other applications and with other video types then this is likely to be due to a missing codec.
http://en.wikipedia.org/wiki/3gp outlines the anatomy of a 3gp file, and from that you can see that a 3gp file may contain audio data in one of a number of formats. Can you please open the video in totem, and then open up the sidebar then choose properties and let us know which Audio Codec is required? -- i don't heard the sound of a video with the extension 3gp https://bugs.launchpad.net/bugs/268103 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
