Early access 0.1.2 and VFR problems

The last hours, updated P2A V3 to 0.1.2 and did a VFR flight. My observations:

1. Voices -> Radio Sound Effects -> Enable Background Noise:
   voices send correctly to my USB headset, but the noise is send to the speakers
   (maybe not always as after one of the many restarts I think, I heared them in the headset).
    
2. Clearance delivery didn't like "Radio Check" (spoken by me but even by "Speak" button):
   "... appears you're on the wrong frequency"
    
3. Validated and filed VFR flight plan between small "INFO" airports.
   Now "RADIO acts as ATC" delivers more functions (not as much as P2A V2), but doesn't handle all of them.
   "Ready to copy VFR clearance" lead me to Center and the same to Center lead me back to INFO.
   The same happened on a bigger airport against tower and clearance.
    
4. Button assignments show button numbers + 1 compared to P3D (V4.5 HF3) and P2A V2,
   say: HOTAS button 7 in P3D and P2A V2 is shown as button 8 in P2A V3.

So I will continue to use P2A V2 at first, but from time to time run V3 and report my findings.
