That's the solution, thank you so much for your help!

Ok yeah, using the same hotkey for multiple scripts isn't supported, so you'll get some odd results with that. You can add this line in your script to get it to happen all at once though:

BFS.DisplayFusion.RunFunction("Set Next Playback Device as Default");

I'm so sorry for the late reply, I thought I had e-mail notifications turned on!

The functions work as intended if they have separate hotkeys.

If you assign separate hotkeys to each function, do they work if you run each one?

Hello, first post and it's obviously a post asking for help. Sorry about that.

Fantastic software, by the way! I've owned a copy of DisplayFusion Pro via Steam for more than a year now, and I can't really work without it anymore.

My problem at the moment is with a custom script. I have a hotkey assigned to set the next playback device as default, and since Windows no longer plays a notification sound whenever the default device changes, I figured a custom script would do the trick. However, I've not really been able to get it to work properly, and I don't know why.

Code
Copy
Select All

using System;
using System.Drawing;

public static class DisplayFusionFunction
{
    public static void Run(IntPtr windowHandle)
    {
        bool ok = BFS.General.Sleep(500);BFS.Audio.PlayWAV("C:\\Windows\\Media\\Windows Notify System Generic.wav");
        }
}

This is the whole thing, with the comments edited out. Might be a bit messy, but it successfully verifies, and it runs properly when I test it out. Half a second pause then the notify sound plays.

However, when I assign the script the same hotkey as the aforementioned default playback device function, the sound doesn't play. Not from my speakers nor headphones.
