No sound from APU after shutting down engines

Hello,
This issue has already been mentioned but from what I see, all topics have been automatically closed. If it’s not the case, please shut this one down.

So here’s the problem : the APU start up can be heard at the beginning of a flight session and it works perfectly. However once the engines have been switched on and turn off after a flight, the APU doesn’t make any noise. I’ve noticed that it will make some sound only if you switch off both engine and then switch on the APU. This procedure causes power loss in the aircraft, it’s ashame.

Did anyone notice this ?

Cheers

Hello there @Cdt_Aupetit,
Sad to hear that it not working. My best option for you is when after you land. Turn on the APU Right away and then after you park at the gate and shut down the engines. You should be able to hear the APU after shutdown. Hope this helps!

Hey @AviatorRyan
That’s my usual procedure : shutting down one engine, start the APU and once parked at the gate shut down the second engine. However this doesn’t work.

Is there other people with this problem ?

What aircraft where you flying ?

Airbus A320 and Boeing 737-800

A320 family doesn’t have an APU sound pack yet but the 737 family do which is odd. It may be a bug.

Yes it’s abnormal, I was wondering if I was the only one experiencing this

I have the same problem as well.

It happened to be just now on the airbus A350

Hi! I am not sure if this will work or not but just try clearing cache of the app (not data, only cache). I do that sometimes incase I get any problem.

Thanks for the advise !

It didn’t work for me though :/

It seems to me the bug is sporadic. For example; the 777 & A350 sound pack works on startup fine. I notice when pushing the sound goes away when moving. The 737,757, work fine most of the time. The pack on the 737 does indeed stop somewhere along the line. What I do is, when close to the gate, I shut off and restart the apu. The other bug is the sound pack disappears when changing weight or calibrating. I leave the app without quitting, then go back in and sometimes that does the trick.
Just a couple of things I see periodically.

It seems like so yes.
It would be nice if it could be fixed. Small details count
