After a hard reset on 8.1 lost all audio. Not only is their no sound, when pressing a ringtone or play in Spotify there is no touch response to show the sound is "playing". Another hard reset did not solve the problem. Clues?
So... A rather pleasant and unexpected outcome.. Even though I believe the device was out of warranty Nokia paid for shipping both ways and replaced my device no questions asked. Hard to complain about that.
