After upgrade to Lollipop yesterday, I can hardly hear notifications, alarms or ringtone - it's all VERY low. Have increased all volume levels including System to full but still no change. Have tried also Adapt Sound to maximum but volume still low and not increasing. What's going on? BTW my wife's Samsung S4 upgraded with no problems and her volume is fine. grrrrrrr Pleeeeeease help if you can.
