1. Are you able to get audio to work during phone calls?
2. If not, what are the specific problems you are having?
3. If so:
a. what operating system are you using?
b. what updates/tweeks need to take place after installing the OS in order for audio to work?
I'm really late to this discussion, but here's a quick summary of my experiences after flashing various OSes and modem firmwares:
1) Yes, audio is working during calls...
2) but sound quality is poor.
3)
a. I am using PostmarketOS with SXMO (latest build). I tried a bunch of different modem firmwares (all stock Quectel) while using Mobian bookworm with Phosh. Since I was never able to get the call audio reliable under Mobian bookworm or trixie, I started to try other OS images and chose PostmarketOS with SXMO because at least the call audio seems reliable (meaning that the modem wakes up from suspend in time to answer calls, all calls connect, and audio is available on all calls). Note that I was not able to get PostmarketOS with Phosh to ever boot fully--it would start to boot but fail to mount the root partition.
b. I have not tweaked anything yet, but would love to do so to clean up the sound quality.
NOTE: I am currently running the official Quectel stock firmware+ADSP image: EG25GGBR07A08M2G_30.204.30.204
I obtained this by contacting Quectel tech support directly and asking them to email it to me directly. It's easy to request. However, I probably painted myself into the corner where if I switch to any Biktorgj's custom firmware, I'll get the corrupt EFS area. That said, I am not particularly bothered by any of the modem's behaviors right now, so I may just stick with the official Quectel firmware.
