Comment 2 for bug 1867539

@Shoichi Chou (mgdesigner) It works here. So... in the audio setup tab and the pulse bridging sub tab, you can remove input and output bridges until there are none left then hit "Apply Audio Settings" so it can take effect. If I monitor the jack graph using either Carla or Patchage, I see the bridge(s) vanish when I hit the Apply button. I can add them back in the same way. For any changes in the audio section to take effect, the Apply button needs to be used.
