I recently upgraded my OS and I have now Ubuntu 12.10 ( the Gnome 3 version ). Since I installed this OS, I have a problem in playing media files or video/audio in general. At random times, ( usually every 2~10 min ) the media playing freezes for a moment and you can hear/see a hiccup in the audio/video. This happens in every media, whether it's a video/audio file from HDD, stream from internet, youtube video, anything.
I have a sample file of vlc playing an audio stream. http://www.sendspace.com/file/42ybmc
Does anyone know what this problem may be? I never had it with Ubuntu 10.04 or with Win7 on the same PC. ( there was not any hardware changed )
