I've been playing the PS3 game (Scandinavian version) for a day or two and all seemed to work just fine.
Now some days later I have major audio issue for unknown reason...
When loading the game I hear sound/audio when the logo videos, start-videos etc plays. If I start a new adventure game I also hear the voice from the Skylander guide (the white bearded character) video. But, as soon the video ends and the game starts for real all the audio is gone.
I have no idea what has happened. But it really ruins the experience

All support help I've found at Activision is: http://bit.ly/RrS7RN
I have tried to delete all my game saves (cant see that the game installs game data) etc, but nothing seem to help.
So, I'm happy to all help that can guide me to get the sound and audio back in the game
thanks
