Connections can't fail as stream creation errors are not being caught or streams waited for, creating zombie connections slowing audio, eventually killing it

pwvucontrol does not suffer from this - https://github.com/saivert/pwvucontrol
pavucontrol-qt has the same issue - https://github.com/lxqt/pavucontrol-qt/issues/289

Repro steps:

1. Download (seems to reproduce with anything, tried this MP3 and a random AAC): https://pixabay.com/sound-effects/happy-pop-2-185287/ and save as TEST.mp3

Unnecessary repro step

2. Create bug.py in the same folder:

#!/usr/bin/env python
from playsound import playsound

while True:
	playsound("./TEST.mp3")

3. Run pw-top in one window
4. Run pavucontrol

Older repro step

5. Run `chmod +x bug.py; ./bug.py` in another

5. gst-launch-1.0 -v playbin uri=file:///home/user/TEST.mp3

Step 4:

Step 5:

This very quickly starts breaking pipewire, causing pipewire/pipewire#3532 (comment 2369336)

Also each run causes this in the logs:
