For the audio file one, I have submitted a bug report: https://bugs.kde.org/show_bug.cgi?id=489597. To summarize, kalarm now uses libcanberra to play audio files, but because canberra does not support flac or mp3 codecs, those cannot be used for audio alarms now. I will set a command alarm that executes a script which first writes a message to a file, then plays an audio file. It will be interesting to see if this doesn't impact file IO. I believe the root cause of the problem is some funky interaction with wayland. When the screen wakes up, I get these messages in journalctl: "kalarm[4487]: qt.qpa.wayland: Creating a fake screen in order for Qt not to crash" - this applies to all my kde apps and components like kactivitymanagerd. -- You are receiving this mail because: You are watching all bug changes.
