Crash on Windows when switching source from a video with audio to a video without

[Cheaterman]

Everything in the title - I'll try to flesh this out later with my own tests, but in short I seemed to have a repeatable crash with the current PyPI wheel version of ffpyplayer on Windows, when switching from a video that has an audio stream to a video that does not ; here's what faulthandler has to say about it:

Windows fatal exception: access violation

Segmentation fault

Note how it's crashing on line 186 of _finish_setup which is a call to self._ffplayer.set_volume(self._volume), which would seem to correlate with the fact that I'm switching from a video with audio to a video without.
