AutoVoice Headset Button doesn't trigger Tasker while device is locked

Hello,
I use a wired headset (Bose SoundSport) when i use the voice search button on the headset remote while the smartphone screen is unlocked, everything works great, but when screen is off, autovoice do not start recognition.
First thing i found out was that i have the problem described in the FAQ:
"When I long-press my Bluetooth Headset’s button while my device’s screen is off, the screen turns off, but the device is still locked. If I unlock it, a prompt that allows me to choose the app to use shows up, but disappears to quickly to select the app. What can I do?"
David T's solution doesn't work for me and also zbombattack's solution description here:
https://www.reddit.com/r/tasker/comments/3ihp95/using_autovoice_with_screen_off/
didn't work, but i found another fix for this:
I checked my logcat and find out the Intent, which is trigger the app chooser prompt.
Then i create a Tasker task too send this Intent while screen was on, the prompt pop up and i was able too make my choice.

Tasker - Send Intent
Action: android.speech.action.VOICE_SEARCH_HANDS_FREE
Target: Activity

But Autovoice still don't start the recognition. Here is the Log from Autovoice:
Recognizer - 2016-06-20 20:07:57.333 - Finishing because recognition didn't start
Recognizer - 2016-06-20 20:07:57.306 - Action: android.speech.action.VOICE_SEARCH_HANDS_FREE

when i use voice search button on the headset remote while the screen is on, my Tasks are working.
Following is in the log when everything is okay:

Recognizer - 2016-06-20 20:47:04.191 - Action: android.speech.action.WEB_SEARCH

And my Bluetooth Headsets, which also working correctly, make a third Action: "android.intent.action.VOICE_COMMAND" and this trigger Tasker event "Autovoice BT Pressed"

Here I see that i have three different possibility actions:
Wired Headset screen off: android.speech.action.VOICE_SEARCH_HANDS_FREE
Wired Headset screen on: android.speech.action.WEB_SEARCH
Bluetooth Headset screen on or off: android.intent.actionVOICE_COMMAND

The Tasker event "Autovoice BT Pressed (2)" is trigger by "android.speech.action.WEB_SEARCH".
The Tasker event "Autovoice BT Pressed" is trigger by "android.intent.actionVOICE_COMMAND"

For "android.speech.action.VOICE_SEARCH_HANDS_FREE" i can't find a tasker Event.

Can anybody help me on these?
