Hi,

Thanks Andreas for pointing me back to this mail; perhaps in all that mail
traffic in the list I've just overlooked this important hint to the
Wiki;

I've played around with the values in gsmhandset.state and with only the
following three changes the audio in both ends improved enormously and
the echo who was facing the called party of his own voice went away
completely:

in control.4:  both values reduced 127-->100
in control.12: value 2-->5
in control.48: value 0-->1

the audio now is reasonable in both ends; with more time (and money :-))
I will see how it could be improved;

to vasco.nevoa a big thanks for this Wiki page; maybe it would be an
idea to explain a bit more all these control.xx values; I'm not an
expert in ALSA / audio staff and so I could only try to deduce from the
names of the values what there meaning and effects *could* be;

Obrigado

	matthias
