Explain this (weird):

[Guest Paraklas]

At random times, phone starts playing Alouette_14kb.wav. Funny thing is, you cannot stop it until it finishes playing the entire file.

You can also go to settings, sounds, and select a sound, and then it will play both sounds together like a mix... Even if you lower the volume, it will still play it loud enough to force you to hide it under something until it finishes.

It's not an appointment, it's not the alarm, it's not a reminder, it's not media player, it's absolutely nothing!

I really want to delete this file as it's getting on my nerves, but I want to find a logical explanation first.

Cheers
