Closing a window hangs for a second & causes pipewire to glitch

## Bevy version

Bevy v0.11.2

## Relevant system information

Archlinux + pipewire 0.3.80 + x11

## What you did

Close any bevy program's main window (if it includes the AudioPlugin).
Close any bevy program using Ctrl+C in the terminal (if it includes the AudioPlugin).

This happens whether or not bevy is actually playing any sound.

## What went wrong

Expected: The window should close (almost) instantly without any audio issues.

Actual:
When I close the main window: it takes about ~1 second to close, and during that time, all of my desktop audio stutters (the last few milliseconds of audio repeat, causing audio popping).

When I Ctrl+C the terminal directly: the window closes almost instantly, and there is a short but loud popping sound.

It's not a major issue but it's a bit annoying as the audio glitching is often quite loud & uncomfortable, especially when it happens during a drum hit.

No source files or tests are named. Reproduce an AudioPlugin-enabled Bevy program closing its window or receiving Ctrl+C on Arch Linux with PipeWire, then trace the shutdown path; done means the window closes promptly without desktop audio stuttering or a loud pop.
