I Wanna turn my sound volume of fs a little bit lower , but it doesn't work with pmdg 737. The engine is still alot volume.

I just wanna lower the volume to hear vpilot vatsim's atc.

Full name signatures here please.

 

The sound is not from the engines but the wind noise, which is loud in a 737. See your Introduction document pg 00.78 for sound recommendations.
