I have recently updated from Fedora 31 to Fedora 32 (on a Thinkpad X1 Carbon — but I'm not sure it's relevant).


Since the update, I'm experiencing beeping alarm sound at apparently random times; which is quite annoying.

What I've noticed so far:

  • The alarms sounds like “a digital watch alarm”, as described in this subreddit. However, unlike what the feedback comment says, it didn't stopped after a dnf upgrade for me. Moreover, I've only used post-released Fedora 32, and not beta (as in the subreddit).
  • The alarm sound is different from the terminal bell / alert sound.
  • The alarm goes off about a couple times a day. It lasts around 10 seconds. Time seems consistent from day to day, and to occur at “round times”: e.g., 08:50, 12:15, etc.
  • Alarms do not seem to be related to any calendar event. As far as I remember, they were still here when I uninstalled GNOME-Calendar.

  • Alarms are not related to GNOME-Clocks alarms.

  • There are no cron jobs running (neither for my user, nor for root)


What causes these alarms? How to disable them?

  • Well, it rang at 10:03 today, so I guess the part about regularity is wrong…

    The sound I hear is actually the /usr/share/sounds/freedesktop/stereo/alarm-clock-elapsed.oga file playing. I'm still investigating which program causes it to be played.

  • OMG. I have the same issue and it's so painfully annoying. For me it always triggers 5min before the daily team meeting. Any solution is appreciated here! Oct 14, 2020 at 8:59

  • @JulianStecklina the quick (and dirty!) solution is to delete/rename the file so that it effectively cannot be played any more. Or replace it with Pachelbel's cannon, as you wish…

In my case, the program playing it was Evolution. The sounds can be turned off in Evolution 3.34.1 and higher (unreleased at the time of writing) in the Settings or via:

gsettings set org.gnome.evolution-data-server.calendar notify-enable-audio false

Here's a general approach to find out what program causes it:

  1. Install auditd (usually the audit or auditd package)

  2. Configure a watch on the sound file by creating /etc/audit/rules.d/alarm-clock.rules with the following content:

    -w /usr/share/sounds/freedesktop/stereo/alarm-clock-elapsed.oga -p rwxa -k alarm-clock

    And load the rule:

    $ sudo augenrules --load
  3. Wait for the sound to happen

  4. Check the audit log:

    $ sudo grep alarm-clock /var/log/audit/audit.log
    type=SYSCALL msg=audit(1604335160.733:102): arch=c000003e syscall=257 success=yes exit=13 a0=ffffff9c a1=23ce800 a2=0 a3=0 items=1 ppid=1664 pid=2045 auid=1000 uid=1000 gid=1000 euid=1000 suid=1000 fsuid=1000 egid=1000 sgid=1000 fsgid=1000 tty=(none) ses=1 comm="evolution-alarm" exe="/usr/libexec/evolution-data-server/evolution-alarm-notify" subj==unconfined key="alarm-clock"
    type=PATH msg=audit(1604335160.733:102): item=0 name="/usr/share/sounds/freedesktop/stereo/alarm-clock-elapsed.oga" inode=3213038 dev=00:24 mode=0100644 ouid=0 ogid=0 rdev=00:00 nametype=NORMAL cap_fp=0 cap_fi=0 cap_fe=0 cap_fver=0 cap_frootid=0

    The comm= and exe= elements may point to the culprit.


Uninstalling gnome-clocks solved the random alarm at 11:00 for me.

There is an issue at https://gitlab.gnome.org/GNOME/gnome-clocks/-/issues/102 which got closed unfortunately.
