Issue with AT+QAUDLOOP=1 on EG25-G

IoT Modules LTE Standard Module

Hello,

For testing the audio hardware on my PCB, I’ve been successfully using the command:

AT+QAUDLOOP=1

This works well on the EG912U modem.

However, I’m encountering an issue when trying to enable this feature on the EG25-G modem. The command does not seem to activate the audio loopback function as expected. I tested it on the latest firmware version:
EG25GGBR07A08M2G_A0.301.A0.301

My hardware setup uses the ALC5616 codec, and all audio settings are left at their default values.

Has anyone else experienced this? Are there additional configurations or prerequisites for enabling audio loopback on the EG25-G?

Thanks in advance for your support!
