My phone doesn't play the notification sound (only vibration) for any app. This is particularly annoying when I get an SMS as I never notice when I get a message.
It appears that all notification sounds are affected, because the StackExchange app notification triggers a vibrate but no sound either. It has been working until a few days ago, and I don't know what I've changed lately.
Settings > Sound, I can "preview" the
Settings > Sound > phone ringtone by simply choosing any of the ones listed. So far so good.
When I do the same with
Settings > Sound > default notification sound, the phone stays silent. It does not matter whether I touch one of the stock sounds or one that I provided myself (which used to work!).
How can I make the notification sounds play again?
Device: Nexus 4
OS: stock Android 4.4.4, rooted.
This problem exists since a few days.
I have tried rebooting the phone, but it didn't help.
The volumes are turned up. In
Settings > Sound > Volumes, all three sliders are somewhere in the middle.
Messagingapp is the default app for text messages. I have Hangouts installed but it's not in use. I also had a few others installed because I wanted to test them, but I have now uninstalled them.
