I've had this problem for months now that adding a picture or video changes the audio and seems to make it more compressed and louder. If I mute the video track the audio is normal. I tried it with all different project settings e.g. resampling and matching media to project turned on and off but nothing seems to solve it. Pretty sure it's in the project and less the render settings. Also tried to reinstall the software, reset all the project settings to default and also tried it on Vegas Pro 15 and 17.

So yeah, if anyone experienced this before or knows how to solve it I would be super grateful since this has been an issue for months now.
