Hi, I would really like to use your software for notifications from trade chat, but the main thing that I need from such software is sound notifications. There are sound notifications in the settings of your program, moreover, you can even choose custom ones, which is good news. Nevertheless, after selecting a sound file, they do not play, although the notifications themselves, according to the keywords I set, are displayed more than correctly. The nice interface and blocking for each notifier looks really good, it's convenient to work with. But at the same time, without sound, I always miss notifications from your program, which saddens me very much. In this regard, I would like to ask: is this my local problem, or is it just a bug? If it's in my hardware or software - I would like to fix it. It’s possible that I’m doing something wrong, because I am not very familiar with programming, although the interface is very simple, and I can’t imagine what I could do wrong, which made me write to you. I also tried to find a solution in Google and the reddit forum, but there is almost no information about Chat cop, basically everyone is discussing your second project, Сurrency cop (which, by the way, I use with pleasure). If this is already a known bug - I would like to know if alerts will work in the future, and whether it is planned to develop the project further (the last commit to the master was last year, maybe you do not want to spend time on this project, because you are doing another cop)
Oh yes, also when creating a new block it is written that the notification keys support regular expressions. I would like to know how this works in practice, maybe it’s worth making a small wiki for people like me who are poorly versed in such things.

I apologize for the long text, I will look forward to your reply. Thanks for your work on the cops.
