I have a small problem in my Canon Xm2. I bought this camera 5 years ago and it only works in weedings ( about 20 hours of registration per year ).

Now my colegs have a problem. They inform me the camera has a problem at the sound. The sound have cuts or a noise like "hiisss". The image is ok. But this problem is in others cameras. Only my camera can read it without problems.

Can you help me? Have i a problem in sound heads? or it could be dirty heads ( sound )?
