My P-43 sounds like whale calls when feeding pellet. Ideas?

[SciGuy]

After 6 years of reliable, reasonably quiet service my P-43 has become to make more than expected noise while feeding pellets. At times it reminds me of whale communication sounds. I've cleaned the fines box and done a careful scrape of the burn pot right down to the auger tube. We've sold the house where the stove is installed and I'd prefer the new owner to have a nice quite stove. I've attached a sound file hoping that it helps your experienced ears with a diagnosis.

Thanks for any thoughts regarding the cause.

Hi - my idea would be to pull the auger out and inspect it. I posted a detailed link recently

Utube decided to show me this video last night, and I don't think I had seen it before. Really good info.

I would wait till the end of the heating season unless it gets worse.
I have heard some noises from mine, but nothing exactly like that. It sounds like a rubbing coupled with resonance
from one of the metal cavities like the auger tube.
I'm sure one of the more experienced members will have a better idea than I.
Please follow up as I am trying learn how to fix/maintain mine.

Thanks for the reply. The recording doesn't really do justice to the sound. It's almost a moaning at times.

The last sound I had was more of a squeak which went away. It was explained to me that it was a stuck pellet in the auger tube. You might have a buildup of dust or a bushing/bearing problem. Maybe even a weld problem on the auger fins. It's possible that auger motor is causing the sound too.
