Alarm clock is silent BFU

matchboxbananasynergy

I just tried it on my Pixel 6. It worked fine for me. Does it consistently not work for you?

On the sound, it's expected for the sound to be different in BFU. Not all of the app's data is available before first boot, so it chooses and uses a default sound, not necessarily what you've picked out.

matchboxbananasynergy It is consistent. I'm on a 6a, though I wouldn't expect that to matter. Maybe something is odd about my settings? My media volume is around 45%, my call volume is around 20%, my ring/notification volume is 0%, and my alarm volume is 100%. Do Not Disturb is off.

de0u You didn't revoke any permissions to the clock app or other system apps, right?

Can you restore the clock app to its defaults by clearing its cache and storage (this will clear saved alarms etc.) and try again?

I reset cache and storage, set an alarm with the default sound, and restarted. That worked. Then I set an alarm using a MIDI file as the sound and restarted. That showed just the animation with no sound. Then I went back to the default alarm, restarted, and that played. Then I set an alarm with the MIDI file, restarted, and unlocked -- that played. So my claim was too strong: it seems to be only non-built-in alarms that don't play BFU. I guess that could make sense, but if there is still fallback code in Clock it doesn't seem to be working.

With respect to permissions, I don't think I have ever revoked anything from Clock. The current state is:

Allowed: Notifications, Sensors
Not allowed: Music and audio, Photos and videos

Is that as it should be?

I had the same problem (alarm muted and only an animation on the screen). Clear cache and storage worked for me, thank you very much. However, I use the standard sound and no MIDI file as described by de0u

Finally I can reduce the timer for my auto reboot - the phone can now reboot automatically at night and I'm still woken up in the morning - perfect!

I'm on pixel 6a, have same settings as OP(reboot after hours of unuse), and have experienced the same issue after recent update. I don't remember if the alarm sound was like "bong", but it was not the one I selected in alarm setting.

Murcielago Thanks for reporting back!

Sorry to dredge up an old thread but I figured this was better than creating a new one. I'm also having this issue on my Pixel 8. I can reliably recreate the problem by setting an alarm a few minutes away, and manually rebooting the phone.

I haven't disabled any permissions for the Clock app or any system apps.
I have cleared the storage and cache for the Clock app.
I'm using a built-in alarm sound.

I did some testing and found that it's only silent if I enable the 'gradually increase volume' function. If I disable that, the alarm sound is different than the one I use, but as @matchboxbananasynergy mentioned, that's just because it is BFU.

Thanks for the report! While this is unfortunate, it's good to know.

I just installed GrapheneOS on my wife's phone that had CalyxOS last night. She has to have an alarm for work and it didn't go off this morning. It's definitely a different AOSP alarm app than the one she had before as it looks different. Which is interesting because it looks just like the alarm app we both had on CalyxOS a couple years ago which did not always work when it should. Then CalyxOS did an update to it and started working consistently. I wonder if they implemented a different alarm app or is there an AOSP alarm app update?

ToughDBlue Mine works BFU every day. Make sure the alarm is set in the owner profile, not a secondary profile. If it's in a secondary profile, it won't go off.

A long time ago, I saw someone say that the option to make the alarm gradually get louder didn't work. I don't think that's the case anymore, but maybe you can try turning that off just to see if that helps. Also, I think some alarms just don't work. Try changing to another alarm sound.

ToughDBlue Is she using a custom alarm sound? The OP mentioned that it worked for them BFU with a default alarm sound but not a custom one: https://discuss.grapheneos.org/d/4027-alarm-clock-is-silent-bfu/5

Edit: is the phone BFU when the alarm goes off?

Thank you for the reply. Yes, it is setup on the owner profile.

Do you mean a custom alarm sound that she uploaded herself? If so, no, she just picked one of the available sounds already available. I don't know if the phone was BFU when the alarm went off.
