Oooooops that where a lot of commits ;)

Its my first time contributing to a Github project ^^

But now everything should work as expected!

[TurboAnonym]

I think i will come back later with an even bigger pull request ;)

Im working on a project and i need AudioSessionNotification::OnSessionCreated too

[AndreMiras]

Thanks for contributing.
When you have many commits, you can always squash with git rebase -i or git reset --soft HEAD~<N>.
I like small pull requests more over big pull requests by the way 😉

Edit: why did you close the pull request by the way?

[TurboAnonym]

i have no clue 😉

i thought with all this back and forth ... that i should make a new request later and add there also:

Get State and OnSessionCreated as well as an example ;)
And add something in to pycaw.pycaw.AudioSession so you can easily access the new functions ;)

i thought it would make it easier for you to test all this if its all in one run ;)

... but youre right small is better ;) then you know where possible errors are

Thanks for the hard work and for fixing the linter.
For your info, you can squash commits and push force in order to make a PR with one commit.
I'll squash upon merge

Yeah it was even fun trying all out and fixing it 😁
Thanks for the maintenance of this project and the info 🤗
