My husband and I both started having this same issue after updating our phones to lollipop. I had given up and was just about to install a 3rd party app when my husband stumbled upon a 'fix'.
It seems that silent mode now means literally no notifications by tone... including alarms. To get around this you will have to customize your interruption settings - paying specific attention to "priority mode". See Menu --> Settings --> Sound & Notifications --> interruptions.
Once you have it configured to your likings, you will find a "always interrupt" button in your notification panel for quick access to your new "silent mode".
I think the original article the husband found was on solvemix. com
Ok... I've found a solution. And it works!
I am on an S5 on EE in the UK.
There seems a lot to do, but there really isn't.
Download an application called Power Toggles from the Play Store - it's free.
Launch it and click on Settings.
Click on Toggle Settings
Click Volume Toggle
Click Enabled Modes
Make sure the Mute and Ring options only are selected and click OK
Now exit the app and go to your widgets.
Add a power toggle 4x 1 widget.
Customise the widget by clicking the Add Toggle button.
Scroll down and choose Volume Toggle from the Hardware Section, about half way down the screen.
Now remove the other toggles by tapping them and selecting Remove.
You will be left with just the volume icon.
Click Done.
Resize your widget.
Now, go into your Sounds and Notifications settings screen and select interruptions.
Tap only allow priority interruptions.
On the screen now, ensure you have selected Events and reminders, Phone Calls and Messages and that Calls/messages from is set to all.
Come out of all your settings and set your phone back so it has sound and notifications again, as normal.
That's it for config.
Now to get into silent mode, tap the widget and it will seem to do nothing, but the Priority icon will appear at the top of the screen.
Tap the widget again and it will turn grey and go into silent mode.
You will receive all your notifications silently, the LED will flash etc but there will be no sound or vibration. Also, your alarm will still work!
Hope this helps.
I followed the steps, still no LEDs, alarm worked and everything else was silent, but no LEDs.
This is how i worked around the alarm on "silent" bug. Go to settings and set up what you want your phone to ring like when you have the audible ringer turned ON. now under Settings > Sound & Notifications, pick interruptions, UNCHECK Events/Reminders, Phone Calls and Messages. (I do not currently have any Priority Interruption Period setup.)
Now add the Priority Only shortcut to your top drop down notification bar, it is a little star icon. your phone should always be set to audible ring with the volume up (mine is about 3/4 up) and what determines if you hear any other notifications other than the alarm is that little star in the shortcut bar.
Think of it this way...
Priority Only = little star icon ON, is the equivalent of kitkat's silent but allows audible alarms. (LED does flash)
Always Interrupt = little star icon OFF is the equivalent of all audible rings, notifications, messages, alarms, etc.
one note that i have noticed with the Priority Only mode turned on is that my LED notifications are no longer color coded but rather always blue. I used to have purple for text messages, green for gmails and blue for calls and other misc, but everything appears to be blue now. Definitely not my favorite, but i can live with it.
I agree this is possibly one of the stupidest things that android has EVER come up with but this seems to be a temporary work around the issue of alarms not going off when silent mode/do not disturb is activated. Because like most of us we use our phones as our alarm clock for work/school/whatever but do not want our phone to ring out loud while at work/school/etc.
Hope this helps someone out there!
Ok here's how to get back Blocking Mode without root
Download: Check out "QuickShortcutMaker"

After installation you can choose this as a widget
Once you are in the app just search "Blocking Mode"
Baaaammm.... there you go.
Save the choice and you now have your old Blocking Mode back
They need to bring back the silent button, why would you ever want your alarms to not go off? Maybe if I am in a work meeting and forgot I set an alarm? Maybe leave the mute but bring back the silent mode! What a pain having to set priority mode. They also removed the selection of silent/vibrate/ring from holding the power button which is annoying. Not to mention the new OS makes my screen much darker than before and my battery life is much worse also. Great update android! Maybe next time warn people that your alarm will no longer work when your phone is on mute, I was way late to work this morning and I am sure many other were also.
