Ok, I was focusing on the speaker side.
alsamixer, tab to go to capture settings, set it to 37 37 Mic2 Mic1 should work, according to my notes, but not recently tested and not tested against real human.
I'll attempt to test it, but something in my userland shuts down system just after boot 60% of time, which is rather annoying.
Hmm. So I tried again, and setting Mic1 and back in the capture settings crashed the modem. Bang, disconnected from the USB.
Next try, and it worked this time.
_Before the call_, set mode to Normal and then Call. Then go to capture, and set 100 100 Mic2 Mic1. Then place a call,
AT+CFUN=1 OK ATD6;
No luck with microphone here :( Using ttyUSB4, AT+CFUN=1 works, but ATD command on it just hangs the USB interface and I have to reload phy-mapphone-mdm6600 to reset the modem.
Test call with real human worked (thanks to Rolf K.), I could hear him well but he reported call was very quiet. And that was with capture settings at 100%.
Maybe the volume also needs to be controlled at mdm6600 end. I'm seeing some AT+CLVL=n with n being between [0-7] calls on DLCI2 in my Android logcat logs.
If you had a register dump from android with mics working, preferably not in speaker mode, perhaps I could try to figure it out?
OK here are four diffs against starting the phone app for regular call, speaker call, and muted versions of them:

Also, I'm connected over cdma right now, not 3g, but I doubt that makes a difference for the microphone.
Found it! Here's what I need to do over n_gsm:
ngsm 1 "AT+CFUN=1" ngsm 1 "AT+CFUN?" ngsm 2 "AT+EACC=3,0" # enable mic ngsm 2 "AT+CLVL=4" # set speaker volume ngsm 2 "AT+CMUT=0" # unmute mic ngsm 1 "ATD${number}" ngsm 1 "AT+CLCC" # list current calls ngsm 2 "AT+NREC=1" # enable noise cancellation ngsm 1 "AT+SCRN=0" # ??? not sure if this does anything
while [ 1 ]; do date ngsm 1 "AT+CLCC" sleep 10 done
So speaker phone call works just fine, I just tested with a human at the other end :)
Hmm let's hope all those also translate to some qmi calls.

Tony
