No sound on notification arrivals.

[nconde77]

Describe the bug Schildi does not play any sound when notifications arrive. I have enabled them in the Android preferences and in the app setup, to no avail.

To Reproduce

1. Go to 'Settings'
2. Click on 'Notifications'
3. Click on 'Notification sounds'
4. Scroll down through Notifications sounds
5. Selec any one (I chose 'Sapo' in Spanish). It plays Ok.
6. Go back with the upper arrows to the main screen and wait for a message to arrive. When it does, no sound is played.

Expected behavior A sound should play on message arrival, but no sound comes out.
