Which system do you use? Android, Ubuntu, OOWOW or others?
Android
Please describe your issue below:
Hello! How is the Khadas interface BT_PCM configured (ALC5651 codec)? Like PCM? or I2S? And how is sound transmitted to the Bluetooth module? Via the UART interface? If you disable the PCM interface, system sounds are transmitted via the Bluetooth.
@DanTretyakov,
Do you want to play sound through Bluetooth?
Is the version built by oneself or is it using the official release? Could you please provide the system version number used?

Not quite right. I want to connect LTE-module SIM7600 to the Khadas with the debug board Captain and feed audio through the PCM-interface.
@DanTretyakov,
The Edge board has an I2S interface, which you can use to connect with SIM7600 and input audio to the Edge board.
