Screen capture always makes a sound

[Anavis]

I have an interesting problem with my lumia 620. Every time I turn the volume down or set it to just vibrate and take a screen capture it still makes a sound even though my volume is down to zero. I have tried to reset and restore it but it didn't help.
Any advice would be much appreciated.

The only way to do it AFAIK, is to turn of 'play sound for camera shutter'. This can be found in Settings > Ringtones+Sounds > then scroll down and untick 'camera shutter'. It's weird, but it works
