Sound: settings get lost
In the control center sound panel, settings for a 5.1 output device the settings get occasionally lost.
Steps to reproduce:
- Open GNOME Settings
- Note current Output configuration Initial (say subwoofer or rear/front setting, which deviate from the default)
- Change Output to something else
- Reboot system
- Back to GNOME Settings, Sound Panel
- Revert output configuration to Initial Output.
At this point I repeatedly lose the settings: subwoofer/rear/front settings are the default, rather than my manually configured ones.
