Popping sound when starting machine

Popping sound when starting machine
I have a resmed s9 autoset.  I do not use ramp, but I do use a climate hose.
Is it normal as I start my machine and it begins to increase pressure at about 4-5cm. h2O it seems to pop air for a second then stops and continues to my set pressure?  Also if I inhale deeply it also "pops" air for a second.  Just want to make sure this is normal as the machine is new. I looked for some other posts and mostly this sound is related to rainout.  I have never had rainout and like I said it happens in the beginning when the machine first is turned on.  

Thanks

Do you feel any moisture when this occurs?

No.  Dry mask and dry tubing.

Do you think it could it be your hose expanding from the pressure?

Just wondering,the sound is coming when the air is reaching the mask.  Is this something other people experience?

Hmmm... maybe the anti-asphyxia valve in the mask is making the noise. Do you have another mask you can try to see if the same thing happens?

Another mask makes same sound.  Sounds like when air hits mask it makes like a thump sound for a second.

I think DeepBreathing is right. Anti-Asphyxia Valve.

if the pressure is too low on a FFM and you exhale, it will force the anti-asphyxia valve to close to avoid permeating the hose with CO2.  This rebreathing feature is typical of all full face masks.  Nasal and Pillows masks typically don't have this feature since your mouth is exposed to the atmosphere.

Could be the mask seals inflating. I can feel/hear mine as they inflate.
