Headset issue, I can hear caller, caller can not hear me

1

mangoH green, wp76xx

when I am connecting headset, I can see headset is identified using device registers

when I am making a voice call, I can hear on headset the caller, but caller can not hear me

please advice what should I do (can be AT command, AMIX command , etc…)

have you tried with AT!AVAUDIO to record your voice first?
This can make sure the hardware and audio setting are OK.

e.g.

at!avcfg=5,1,2
AT!AVSETPROFILE=5

AT!AVAUDIO=1,1,/home/root/test.wav
//here you should be able to hear your audio file

at!avaudio=1,0

AT!AVAUDIO=2,1,/home/root/record.wav

//here you can record some sound
at!avaudio=2,0

that did not worked:

file in record step was created, but when I played it on PC I did not hear anything
when trying to play any wav on the green board I could not hear anything

btw, when I am making a phone call I can here sound using the headset on the green, but the caller cannot hear me

at!avcfg=5,1,2
AT!AVSETPROFILE=5
AT!AVAUDIO=1,1,/data/sounds/beep.wav <— I do not hear anything, not locally and not on remote phone
at!avtoneplay=0,1,2000 <— I can hear beep locally (not on the caller side)

I can hear the wave file and record a wave file in mangoh green board:

root@swi-mdm9x28-wp:~# microcom /dev/ttyAT
at!avcfg=5,1,2
OK
AT!AVSETPROFILE=5
OK
AT!AVAUDIO=1,1,/home/root/0-to-9_8k.wav
OK
AT!AVAUDIO=1,0
