I am not sure what this means, but i already saw it too. Maybe wrong alsa 
state or that the device is already open by some app.

Can you try e.g. afer reboot manually switch with alsactl between 
gsmearpiece.state and speaker.state?

I should have kept my old GTA04A3 - but now it's too late, so cant test it 
myself. But IIRC Neil has A3 too he can test too.
