How to reproduce:
Result:
After about 5s, the timer alarm sounds for about 0.5s and is mute afterwards. If there's music playing in the background (from the walkman app), you may get just a short 'blank' in the audio stream (also about 0.5s long).
This beahavior occurs...
Thies doesn't happen if the screen is on and the clock app is running in the foreground.
I've had no problems with the normal alarm (the ones you set to occur at a specific time).
What can I do?
Just tried that myself and you are correct... I also tried allowing the screen to turn itself off by setting the timer beyond my screen off time and the same thing occurs.
What software version are you currently running ?
I'm on the newest 23.0.1.A.0.167
I'm also running 23.0.1.A.0.167.
The strange thing is, the normal alarm seems not to be affected by this.
Agreed, I use the alarm everyday and it functions correctly... Not sure what other options to explore, but then again I don't really use the Timer but that doesn't mean it shouldn't work as it should 
A colleague has a Z2 with the software version 17.1.2.A.0.314. For him, the timer works fine. This is probably a bug with the newer software versions.
I have this problem too!
Android 4.4.4. Build 23.0.1.A.0.167.
Happens on my Xperia Z2 Tablet (SGP512, running Android 4.4.4/Build 23.0.1.A.4.30), too. 😕
Yes, your description of this problem is very accurate and it is very annoying. I use the timer frequently when cooking and this problem have caused several runied dinners already 😞 This reminds me of the sleep of death problem with xperia V, only this problem is consistent. Please fix this or provide a solution.
I have the same problem and I just can't stop myself thinking why is this problem still happening to us with such a huge company as SONY.. It's been months since this problem first noticed and still not fixed.. This kind of problems may seem like so little but it can make SONY loose custemers like me who are so annoyed by not feeling that they are cared at all..
