No doubt you have a problem with a pad or a spring down at the bottom of the instrument. My first guess is that it's a spring.

Work the keys down there. The ones on the right are supposed to stay open unless you press their keys, the ones on the left are supposed to stay closed. If one of the springs has broken (worst case) or slipped off, then they won't be doing that. From here, it sounds like the B key is not staying open entirely, and because it's muffling the hole you're having, in effect, a slow leak.

If that's the case, look closely at the little rod-springs--see if one of them is poking out into thin air instead of nestling in the little notch where it's supposed to be. If so, get something like a jeweler's screwdriver or tweezers, and push that wayward spring back into place.

If the spring is broken off--which you may figure out if there's a little notch with no spring to go into it--then a professional repair is essential, but you can do a temporary patch by getting a rubber band. It will require some inventiveness, but put the rubber band around the key that needs a spring, and wrap the rubber band around the clarinet and find a place to anchor it.

If it's not springs, look closely at the pads on all the keys in the bottom half of the clarinet. One or more of them will probably be bad--probably not missing altogether because that wouldn't create the muffled sound, it would just play the wrong note. If you find a bad pad, of course you'll want a professional repair, and it doesn't take them long to do it in most shops. Your band director might even keep a few spare pads and some glue on hand and might do it for you--tho' the professional repair shop would set the pad nicer. If you can't replace the pad, the only alternative is to get some cigarette rolling papers (the variety with no glue) and lick one of them and stick it onto the surface of the bad pad, then press it hard against the hole so that it seats. Or try chewing gum to fill in big flaws in the pad, covered by cigarette paper. Or just block the hole up for the entire concert, if you don't need that note, using a small piece of black electrical tape.
