I recently adopted a red-footed tortoise, pleasantly named 'Mishelle' or 'Shelly', and I found our she was making a whistling or popping noise as she was breathing. Thankfully her mouth wasn't open nor were there any signs of bubbles around her mouth or nose. According to a reptile medical sight, it meant there was low humidity in her box. So I bought her a humidifier and am currently using a deep plate as a bathing/basking area until I get paid Thursday to get her a real basking dish.
