This function assumes `ref` never reaches 0, is it guaranteed though?

I'm not too happy with this merge request, honestly... mainly because I'm unable to remove the `IAudioSessionControl` implementation that currently lives in the drivers, as it's accessed in `IAudioClient::GetService()`.
@huw Should I perhaps just build `audiosession.c` in each driver instead of `mmdevapi` for the time being?

I'm not Huw, and you should probably listen to him over me, but in that case I would suggest moving the `AudioClient` object first.

Well... moving `IAudioSessionControl2` first is clearly not the best approach as tests didn't reveal the issue.

No worries, thank you very much for your input!
I should indeed do that and export a function that returns a struct object containing the various vtables.

Actually, turns out all interfaces are interlinked. Moving a single one would require building quite a few bridges between `mmdevapi` and driver.
I think my initial idea (building `audiosession.c` in each driver) is the sanest approach. Let's see how it goes.
