avfoundation crashes on macOS

[starptr]

Describe the bug
On macos, when playing video containing spatial audio (eg. DTS-HD MA), selecting "Spatialize Stereo - Fixed" in the Sound menutray for the current device (eg. airpods pro) stops the video and automatically selects another device in the Sound menutray.

To Reproduce
Steps to reproduce the behavior:

1. Configure mpv through mpv.conf to use avfoundation by writing: ao=avfoundation in ~/Library/Application Support/jellyfin-mpv-shim/mpv.conf.
2. Start the jellyfin-mpv-shim cli (no gui).
3. Play a video with spatial audio (eg. DTS-HD MA).
4. Select "Spatialize Stereo - Fixed" in the Sound menutray.

Expected behavior
Mpv should keep playing the current video and playback spatial audio for the current Sound device. This is the behavior observed when launching the mpv application bundle directly and using the "open URL" feature instead of jellyfin-mpv-shim.
