Ho to get notification on external speaker only for notifications on Samsung S2

Hello' I'm testing this app on Cyanogenmod 10.2 rom (Android 4.3) but I could not get the result that I expect. I select the following options, I start Poweramp player and my scope of course is to get music playing on headset and have alarm notification on the external speakers in the morning.

Notification behaviour:
Selected: "Notification to speaker" and "Ringtone to speaker"

Media Audio:
Let app decide -> I get music and alarm notification only to headset
Wired Headset (with mic) -> I get music and alarm notification only to headset.
Wired Headphone -> I get music and alarm notification only to headset
Speaker: I get music and alarm notification only to speaker.

I could only get it working using "Tasker" app but it is not 100% reliable and we should consider that if put time conditions on Tasker we should remember them if we need alarm notification on unusual time.

Please, is it Soundabout able to work as I expect? Something wrong on my setting?

Thank you in advance
