Jolla alarm and notification sound quality
The included Jolla alarm and notification sounds contain a bit to much noise which you can hear from the internal speaker not only with hifi headphones.
The sounds are not faded out enough at the end. You can hear a short sound peak at the end. You could also analyse the ringtone waveform with e.g. audacity at the end of the file.
The "jolla-alarm" sound contains distortions/scratches.
