Is it a Quattro mask which you are using, because this happened to me once after washing the mask. I found out that the little rubber plug at the bottom of the mask had become partially detached. When I had pushed it back in place, the noise subsided (which I had thought was an increase in pressure), and I was able to sleep again.
