You really need to check and test all the audio files for the Saab 340. They could cause major issues.
Make sure they are in the proper wav format and test them. Not sure what you are using to create or test them.
But they have issues. I've edited and produced audio for over 30 years. So I do know a little bit of which I speak.
I own the Saab 340 and just don't fly much anymore. But I thought I would let you know in my latest scan of wav files to check for errors in the
X-Plane directory your's are the only ones that spit out errors. And that's not a good sign.
