I am currently working on EG915N on Ubuntu 22.04.
I activated UAC using AT Command :
After modem reboot, Ubuntu detect the modem as sound card (Android).
I set up this sound card as Output and Input Device.
I finally tried to use aplay and tinyplay to test as mentionned in “LTE Standard UAC Application Note” in a phone call :
ATDXXXX OK tinyplay music.wav -D 0 -d 0 -c 1 -r 8000
sox music.wav -t wav -b 16 -r 8000 -c 1 music_8000_16b_1c.wav aplay music_8000_16b_1c.wav
I am able to hear the song but far way and very “chopped” and some noise, it’s difficult to understand something.
Is someone has experienced this issue before ? Or am i missing something ?
