So is basically everyone who is being called with a Neo Freerunner
having at least a little echo of her own voice? At some point I had
often the problem that the receiver heard everything she said very
aloud about 1s later, now in at least my own tests it's merely quite
quiet repetition that doesn't always even occur (gets cut off by
something, eg. a noise filter). I used gsmhandset.state from here:
and also stored it at /etc/asound.state.
