I just noticed today that I have no sound of thunder generated during a thunder/lightning storm. I was flying today during a huge thuderstorm with frequent lightning everywhere. There was the sound of rain but no lightning sound.

 

I am using PMDG 737 with REX textures and ASE2012 for weather generation. I selected the environment slider in FSX sound menu all the way up, I turned up all the sound selections on the PMDG FMC, I selected the high quality speaker output on FSX...nothing seems to work. I checked the thunder files in FSX, they appear to be working fine. I tried different aircraft with the same result. I didn't see anyhting wrong in the fsx.cfg file either.

 

Anyone have any thoughts of why the thunder isn't working? Or has anyone experienced this problem before. I searched the topic, but I only came up with one thread that didn't look like it was resolved.

Simmarket has a Perfect Flight Environment Program and Flight One has an Audio Environment program too. I haven't heard the thunder sound either but I fly mainly PMDG's 737 and don't expect to hear stuff outside during a flight. It might be a little unrealistic in some cases with aircraft internal environment sounds drowning out external noises. Do you hear the sounds while sitting on at a gate with all engines off? That's when I would expect to hear them. Sorry I can't be of more assistance.

 

Best regards,

Jim
