[C2] Alarm randomly goes silent

[JulienBlanc]

REPRODUCIBILITY: Random
OS VERSION: 5.0.0.21
HARDWARE: Jolla C2
UI LANGUAGE: French
REGRESSION: Yes, over XA2 4.6.x

DESCRIPTION:

Setting up an alarm before going to sleep, I expect it to be noisy on the morning. What happened is that the alarm did trigger, but without any sound. No vibration as well.

PRECONDITIONS:

Set up an alarm. Differences between when it works and when it did not are mainly that i restarted android support and network connectivity.

Observable difference is that vibrations did not work anymore. When vibrations works, alarms seems OK, when they do not, it fails (empirical guess).

STEPS TO REPRODUCE:

1. Set up an alarm
2. Put the phone in a mode where vibrations crashes (see other relevant bugs), I remember having killed ngfd but this is actually part of the solution (vibrations comes up again, and alarms seems to be fine again).
3. Wait for the alarm to trigger. It triggers correctly, but no sound comes up. It is also difficult to ackowledge it.

EXPECTED RESULT:

My phone wakes me up in the morning, so I’m not late for work. This is an important use case

ACTUAL RESULT:

My cat woke me up in the morning. I’m grateful I had a backup.

MODIFICATIONS:

Stock install, developer mode enabled.

ADDITIONAL INFORMATION:

Nothing relevant

My cat woke me up in the morning. I’m grateful I had a backup.

OT: I love that backup .

I’ve had this issue as well, over the past few days. One thing I’ve also noticed is that the alarm will be sounding silently, but if I dismiss it, it will sound again silently around 30 seconds later, despite the dismissal.
I started restarting before bed, that seems to solve the issue.

[JulienBlanc]

Restarting indeed works, as well as killing the ngfd process.

About the difficulty to dismiss the alarm, it’s also the case for calendar events: dismissing them from the full screen notification fails, but works from the notification area in the events screen.

Sounds related the bug

[Clock app] Scheduled alarms fail

For a couple of times now I have overslept because the alarm in the native Clock application fails to go off at the scheduled alarm time. When I wake up later on and look the Clock application, the active alarm at 4:40 is still active and nothing seem to have happened at the scheduled time it should have alarmed. The chosen hour comes, but nothing happens. The issue does happen on the current OS, but it did also happen in previous iterations too. Started happening “as of lately”, I wish I coul…

For me, it seemed system sounds in general were silenced, this work around mentioned here seems to have fixed it for me (working ok for the last week or so):

Vibration crashes, causes (?) lags when activating an app's top menu

One workaround that we just shared @ Helsinki support session is to disable some common vibra places. So from Settings → Sounds and feedback For the top Vibration combo box select “Never” Disable “Touch screen vibration” from “Feedback” section.

Still occurring with 5.0.0.29.

Behavior is a bit different, though, acknowledging the alarm works fine. But it’s still silent. (I’m not completely sure it occurred, because it did even not show up as missed alarm). I also checked that it did not work with timers.

In case it’s relevant, the lag due to vibration seems to have been fixed (there is no longer a lag), but the phone still does not vibrate.
