Hi all!
After upgrading to 1.2.0 alpha i can't change volume handling in media portal. On previous version i always used MP to control master volume, becouse it useful when launching games. But now after upgrade i only can adjust wave volume. In MP configurator this settings are not adjustable. Any ideas? May be there are some setting in config files of MP to take all this back? And set MP to control master volume?
Here is the screen shot.
