example_volume_app

Description of problem: all audio playback stops when I seek through media and when I change the volume inside the application while it plays.


Version-Release number of selected component:
kernel-5.12.5-300.fc34.x86_64
pipewire-0.3.28-1.fc34.i686
pipewire-0.3.28-1.fc34.x86_64
vlc-3.0.14-1.fc34.x86_64
firefox-88.0.1-1.fc34.x86_64


How reproducible: every day, multiple times, but not always.


Steps to reproduce:
1. run media in vlc or firefox.
2. seek back and forth.
3. increase and decrease your volume in the app.
4. if that doesn't trigger it, try doing it with your mouse scroll wheel.


Actual results: audio suddenly disappears and you've to restart all of your applications.


Expected results: no interruptions, continuous audio playback.
