The audio volume (playback as mp4 and in the app) has changed in many of my videos. I am using version 8.5.2 of Camtasia Studio on a Windows 7 machine. I recently got a new machine and monitor, but I don't know if that has anything to do with the problem. Videos that were created before, as well as ones created since, I got the new machine suddenly have an issue in that the volume is extremely low. I have checked the settings in the app, in Windows, and in the monitor, and everything is maxed out.
