mate-volume-control can't manage sound theme

[cmadamsgit]

Expected behaviour

Set/change the sound theme options in mate-volume-control

Actual behaviour

When I run mate-volume-control, it shows Sound theme: No sounds and the Choose an alert sound: and Enable window and button sounds sections are grey. I can change Sound theme to Default, then the other sections are un-grey (although there's no themes other than Default), but the change doesn't actually apply. No sounds are enabled, and closing/reopening the volume control goes back to "No sounds".

If I change Sound theme to Default and uncheck/recheck the Enable window button sounds box, it does actually apply the settings (I can get a speaker bell from xterm for example). However, if I rerun mate-volume-control, it resets the settings to "No sounds" without even changing anything.

Steps to reproduce the behaviour

MATE general version

1.26.1

Package version

mate-media-1.26.1-1.fc37.src.rpm

Linux Distribution

Confirmed here, but note that I do NOT have a working install of libcanberra on my custom GTK 3 builds. This may or may not be the intended behavior when no system sound themes are installed. I see the combo box showing "No sounds" and "Default" and never took any steps to install a sound theme for this. On my setup such sounds can interfere with recording audio so are not used

I can play with /usr/bin/canberra-gtk-play --id="complete"
and when I set No Sounds I get a Failed to play sound: Sound disabled

However, system sound from keyboard when pressing BackSpace still play when No Sounds
