2 years ago first I want to start off with letting you know that the code works with python 2.7 only. I stumbled across some kind of a hole where I am able to get notifications when other applications start and stop playing. This is not something that is supposed to happen and every time I port he code to python 3 that feature stops functioning.
First I have to explain the structure to you so you understand how things are put together.
You have a device and that device has endpoints. This is where it can get a bit confusing. An endpoint is either an input or an output, i can be a single jack or it can be multiple jacks or it might not be a jack at all (i know right).
so when you open up your sound manager in windows you see things like headphones, speakers, spdif those kinds of things. Those would be endpoints.
You need to know if you want to change the volume level on a global level or do you want to change the volume for only the headphones or the speakers.
Switch default device, i mean "Speakers" to "Headphones" and how i can get event callbacks for it?
yes
Can i switch Channel Volume Level? I mean change volume level just for "Chrome.exe" or "Skype.exe"
no, application controls are called "sessions" and only the owning process of that session (or windows sound manager) is able to do that. could you imagine what it would be like if one application could change another applications sound settings. Microsoft did not release the API for changing the default sound device for this same reason. At some point some developer for Microsoft did leak that API to the public and that is the reason why we are able to do it.
We are able to get events when a session starts and stops playing, this is not something that is supposed to happen but for some reason it does.
but in pypi.org i found this lib for python 3.7-3.9 and without descriprion and other links and by other author.
TY for letting me know this, I am going to have pypi pull it down as there is no credit given to me and I am the original author. And to make matters worse, it is an improper conversion and it is going to have issues. The Windows data types are not properly set up for a 64bit python for starters, they didn't change the singleton metaclass to work properly with Python 3 and there are other things as well.
It looks like the person that made the change did update the code in attempt to be able to change session volumes of other applications but that is only going to work if the session events continue to work and every time I have made the conversion they stop functioning. I was never able to set the session volume levels so the code they added might not work.
Mostly what the person that added that to pypi did was change the print statements and change the import statements. I personally find it exceedingly rude that the person did not ask if they could post it on pypi and that they provide no link on how to get support for their modified version.
give me a day to hammer out an example for you an I will once again screw with getting it ported to Python 3.

Hello! Thanks a lot for you'r lib, it's fantastic!
You have done a great job and made the most powerful lib for Windows Core Audio API! Thanks a lot yet!
But can u make some 'quik start' or some little examples for each "ability". I mean just little example how change 'Volume Level' or 'mute' e.t.c
I'm just started programmon on python and some things is hard for me yet.
Can anyone give some suggest or couple-string-example how:
P.S. I can't understand some thing. In other issue author says he don't update this lib for python 3.7+ but in pypi.org i found this lib for python 3.7-3.9 and without descriprion and other links and by other author. It's mean good news for us and you finally updated for python 3 or it's some other people did it?
