Alarm clock broken

[vs6xfx]

After update to OS 10.0.14267.1004 with FW 1078.38.16025.39005 the alarm clock is no longer working properly. Volume of alarm reduced to one third even media volume set to max. But preview the alarm sound is OK. Anyone have clue on this?

TRY: Remove battery+SIM1+SIM2+SD card wait 1 minute, replace all back, restart 950XL....Tada!:winktongue:
