SUMMARY *** I file this report in the space although I am not 100% sure that this is an issue of the integrator or something else. I run KDE 5.26.4 on Fedora 36 with all latest patches applied. I don't know which update broke it since I update the system daily but at some point between 09 Jan 2023 and 20 Jan 2023 an update broke the notification sounds from the browsers I use (Firefox and Chrome). I can get notification sounds for the emails I receive, regardless of the email provider (Google, Outlook etc), I get *visual* notifications for chat messages (Gmail/Google chat, Mattermost etc) but I have NO sound for them. The chat notifications are completely silent. Since I haven't change anything in my configuration, I consider this a bug. ***
