A321 APU Sound?

When sitting at a gate in an A321 today, I noticed that the aircraft was making a distinct noise. I thought it was another aircraft with its engines on, but no one was around me. When I turned off the APU, the noise also went away. Then I turned it back on, the noise came back! Did Infinite Flight add a minor update to the A321?

Infinite Flight added APU sounds to the generic sounds, pretty cool!

But it doesn’t have APU sound inside cockpit, only exterior. That is the only thing they need to fix it ASAP!

The 777 in real life is a good example

Yes it does. Quietly maybe, but it’s there.
