Thanks for the tip. However I think that the point here is that there seems to be a problem with the remote and that they should work fine for many hours of play. My original remote became faulty after just 15 hours play!
If you are prepared to play Zelda for a couple of days without the sound then that's fine, but I think most of us expect the remotes to work properly especially as they are virtually new. Has anyone got a response from Nintendo about this issue?
On a more positive note, so far Zelda is brilliant so congratulations Nintendo!
