Cross-posting here in General for visibility, since this section gets a little more traction.
Many, many, many years ago I wrote a Lua script for StrokeIt that would allow changing the system volume.
Since then, the script has stopped working, and I stopped maintaining it. It had some dependencies that I didn't bother to keep up with, and it required some user editing of the script to get it to function as intended -- not exactly the most friendly of experiences.
Today, I decided to re-write that functionality as an actual binary plugin for StrokeIt, and release it as open source.
You can find the repository here: https://git.sdbarker.com/sdbarker/strokeit-volume
You can find the binary release here: https://git.sdbarker.com/sdbarker/strokeit-volume/releases
If you would like to discuss the plugin, please head to this thread in the Plugin Development area -- https://www.tcbmi.com/strokeit/forum/read.php?5,243906
