You can change volume in NeoControl, but you have to do it during call. That 
means: make a call, press AUX to switch to application list and run NeoControl 
and then play with the volume controls. Once you are happy you can use the 
save button.

You can do the same using alsamixer e.g. from ssh during call, but in this 
case you have to maually store the state - e.g. with:

	alsactl -f /opt/qtmoko/etc/alsa/gsmearpiece.state store

I am afraid that with louder mic the other side will start getting echo. But i 
havent checked it yet.

I hope the situation will be much better with HW routed sound. There are good 
chances that the echo cancelling will work better and it will allow louder 
playback/mic volumes. Then should also disappear the problems that some other 
application has soundcard open and the software routing program cant open the 

GTA04A4 is thanks to Christ van Willegen on the way so i hope i will start 
playing with it soon.
