I can’t hear any beep noises from BB-8 in the scene you describe mate - on the cam version or the bluray (31m, 48s). That’s not to say they are not there - but just I can’t hear any…
BB-8 does however makes beep noises in the scene you describe on the official teaser trailer, here:-

It’s definitely there. I’m not going to go ahead and post clips before the official release of the film, but I’ll make a short clip a week from now comparing the two.
Cool - the only thing I’m hearing in the scene where BB-8 rolls up to the Falcon is the sound of the TIE-Fighter flying overhead and then an impact blast sound, along with the orchestra chase tune throughout the scene.
There could well be some audio differences - I’m off to book in an ear test 😉
