Hi Enrico! I started to investigate a bit more and I found out to use it, for both GTA01 and GTA02 :-D

As you, I am lost with that explanation, but further investigation revealed a probably better one: http://thread.gmane.org/gmane.comp.handhelds.openmoko.devel/964 Here the mixer settings you need to change (values in brackets): - Playback (GTA01) Neo Mode [GSM Handset | GSM Headset] (GTA02) DAPM Headset Mic Switch [ON] (both) one of Left Mixer Sidetone Playback Sw [ON] Right Mixer Sidetone Playback S [ON] - Capture (both) ALC Mixer Mic 1 [ON] With this configuration, however, the problem is that xev reports the following event if the headset button is not pressed: KeyRelease event, serial 30, synthetic NO, window 0x1000001, root 0x3d, subw 0x0, time 1856476, (236,274), root:(240,320), state 0x0, keycode 127 (keysym 0xff13, Pause), same_screen YES, XLookupString gives 0 bytes: XFilterEvent returns: False Should not be the contrary, i.e. reporting a Play event when the button is kept pressed? Anyway, I think I would stop here and go back to other issues, now ;-) Thx, bye, Gismo / Luca
