Hi, everyone

I have recently got my Neo buuzfixed.

Based on #2121 [1] I have tried two alsa states: 

- [2] gsmhandset.state.new (supposed to be the correct one): I got echo and the 
voice heard on the other side is very distorted
- [3] gsmhandset-a7.state: I got good sound, no echo at all, but volume is 
lower than gsmhandset.state.new (but higher than before buzzfix, of course)

Starting with gsmhandset.state.new I have lowered  'Mic2 Capture Volume' to 0, 
and that way, I have no echo, and voice is crisper and louder than -a7. 

Does someone has the same problems?
Is it possible to let Mic2 gain on 3 and control echo with any "stronger" AT
