Dear sir,
Please check which codec type are you testing? The default codec is ALC5616. The default configuration is shown below.
[2020-06-18_19:05:54:214]AT+QDAI?
[2020-06-18_19:05:54:225]+QDAI: 3,0,0,4,0,0,1,1
Dear Kirill,

I tried these settings but I still can’t hear the sound in my head phones.
I also tried to check the sound vie PCM out: I removed the sound codec from the board and set the PCM out with AT+QDAI=1,0,0,0,0
I performed the outgoing call from the board and accepted the incoming call on the external phone.
Then I said some words to both microphones during 7 seconds.
Then I finished the call.
I went to the folder Qnavigator_V1.6.9\AudioPath_20200612091236028
and found the file AudioOut.wav with zero length
I don’t have any other idea why the sound cannot be heared or recordered.
What are other possible reasons may affect the sound absense?
