Depends on your speakers and how your setup is made. Use just one device to control volume.
I mean, look at where the volume comes from in line. Here are places where I control my volume of Emperor:
- There is VLC player that has volume control.
- Then there is PC output (sound cart from PC)
- And then there are speakers that are attached to computer that have volume control of their own.
So, in this case you have to look at the last controllable volume that you have in the line.
Mine is ‘‘external speakers’’ as they have their own volume controller. I just found best volume that is below the one that makes my ears hurt and itch and just left it there (I even made a small mark). All the vlc and pc output is on 100% (pc output is 100% because there’s no distortion for me). Those I do not change.
If your speakers do not have volume controller in them, choose either vlc or system volume to control the sound of subliminal and remember the settings.
Basically 75% of system volume will never be the same for everyone. If you put vlc to 10%, 75% of system volume and speakers to 2/10 it is much different than vlc to 100%, 75% system and speakers to 7/10.
