SUMMARY Thunderbird still plays sound for incoming mails during "do not disturb". This hasn't happened before in 5.27 and it defeats the purpose of DND. SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20240311 KDE Plasma Version: 6.0.1 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 Kernel Version: 6.7.7-1-default (64-bit) Graphics Platform: Wayland Thunderbird: 115.8.1
Unfortunately this would be a Thunderbird bug. DND mode can only suppress sounds that come from notifications; if Thunderbird plays the sound via the main UI rather than a notification, we can't do anything about it. I know yo said this didn't happen in 5.27, but it's possible that Thunderbird itself was updated around the same time and made this change coincidentally. Regardless, please submit a bug report for Thunderbird.
