Hi,
Nowadays, this could facilitate having the PipeWire pulse server without installing PulseAudio server it-self. I suspect that this will solve my situation regarding #989800. In fact libcanberra-pulse is recommended by gnome-control-center probably for the reason of my trouble. Sure libcanberra is a bit obscure to me as I was thinking that libcanberra- gstreamer and gstreamer1.0-pipewire will do the job in GNOME as alternative to libcanberra-pulse and pulseaudio, even regarding sound tests in gnome-control- center. Another mystery is that the alert sound/theme selected in gnome-control-center is not handled by any gsetting property, isn't it? What ever the current alert sound, there is: $ gsettings get org.gnome.desktop.sound theme-name '__custom' Moreover its default value is 'freedesktop' but it is not a « stable » value. In another words gnome-control-center will change it to '__custom' whatever the sound alert is selected. It is easy to check: $ gsettings reset org.gnome.desktop.sound theme-name $ gsettings get org.gnome.desktop.sound theme-name 'freedesktop' $ gnome-control-center # then select any alert sound and quit ALSA lib pcm_dmix.c:1075:(snd_pcm_dmix_open) unable to open slave (gnome-control-center:12136): sound-cc-panel-WARNING **: 20:38:57.759: Failed to play alert sound /usr/share/sounds/gnome/default/alerts/drip.ogg: Not available Note: this last message is another strange story because the file exists on my system but it was not played due to my initial trouble. And then: $ gsettings get org.gnome.desktop.sound theme-name '__custom' Also why this value is not 'gnome' in fact: $ ls /usr/share/sounds/ alsa freedesktop gnome purple sf2 sf3 sound-icons speech-dispatcher that should be a bit more intuitive to me. Thanks, Patrice
