In the THX optimzer, there is no sound coming out of the sub (or indeed, the amp's tone test)... but during the movie itself, there's definately sound from the sub. Is that normal?

What sort of volume level is your amp/receiver set at? The THX optimizer test tone is volume related, if your volume level is low, its doesn´t appear to make much noise (to your ears!). There should be something there.
