-- Information about the crash:
Systemsettings crashes after opening sound -> switching to a different module
-> sound. This does not seem to occur on other modules.

Not sure if related, but after the update to 6.1.0 the device names in the
sound applet are different. However they have not changed in the settings
module. For example:
HDMI / DisplayPort (GP104 High Definition ...) -> HDMI 0

The crash can be reproduced every time.
