I would like to mention one small bug I found.

Let's say that I have to audio to play every 10 minutes.
The audio plays at 3.10pm.
I close my laptop lid at 3.12pm.
The laptop sleeps/suspends.
I open my laptop at 6.48pm.
As soon as the laptop wakes, the audio plays (this is the bug).
The audio also plays at 6.50pm (this is what it should do).

So it seems that when the computer is asleep, it 'builds up' one audio event, which plays as soon as the computer wakes up again.

It could have a practical purpose, too. Imagine a folder of positive affirmations, where a random one would play every hour or so, to inspire you. Kind of like an audio version of mouser's Popup Wisdom.

That's exactly the way I'm using it! Not a prank at all.
And if you don't want to use it that way, imagine having just one simple 'beep' sound that plays every 15 minutes, or every hour, to remind you of the passing of time and to stop procrastinating. I imagine some people would be happy to use it just in that way, without the random aspect. To do that, you only drop one audio file into the folder, and that's all the app will play.

@publicdomain Thank you for this latest release! I really appreciate your work with this app. It works and I use it every day.

There seems to be a bug when you have the app set to start with the OS. When you reboot the PC and the app starts, it does indeed start, but it doesn't work. I get an popup error message saying Unhandled Exception has occured, and "Access to the path "C:\Windows\system32\SettingsData.txt" is denied. Even though I don't think it should be putting anything in the windows folder. The app itself is in a folder on the desktop.

I will try and reproduce it again and see if I can list the steps required to do so.

For the future, I would only suggest, but only if they are not too much work:
1) trying to mute the audio if the windows sound system is already playing audio (from a video etc.) (code in one of the posts above in this thread).
2) a scheduling option of some sort. (this user interface for scheduling looks interesting: https://softorino.com/volumeconcierge2/)

Hello Vic.

Thank you so much for releasing this latest version!

I tested it and found that:

1) The new mute option works well
2) The new minimise to systray button works well
3) The new settings xml file works, and is easy to understand

I also found that this bug:

There seems to be a bug introduced in this latest version. I have it set to play a sound every 5 minutes. Every 5 minutes, it sometimes plays a sound for only one second, then cuts that off, and starts another sound instead. It doesn't happen every single time, but it happens quite often. The previous version didn't have this problem as far as I could tell.

is still happening.
