Hi to all, I have been using banana pi pro and m1 for some years as mini PBX with asterisk, due the stop of bananian's development that works perfectly but now is obsolete and vulnerable, i'm testing armbian but registered prompt audio sounds choppy and i can't find reasons, I tried to move files in ram disk, use usb to lan interface, increase process priority, use performance ad cpu governor, also tried Armbian 5.83 Bananapi Debian stretch next, same problem. Any suggestion ? Thanks advance.

Providing logs with 

armbianmonitor -u

 helps with troubleshooting and significantly raises chances that issue gets addressed.

Hi, http://ix.io/3Z0u 2 posts then 24H stop, I had too much time to wait and tried image from https://sd-card-images.johang.se/, debian arm sid vanilla, it works great, perfect audio. However I'm here if we want to investigate and try to solve the problem, armbian can also works great.

What's the version of the Kernel on the image you installed from sd-card-images.johang.se?

Linux version 5.17.0-1-armmp (debian-kernel@lists.debian.org) (gcc-11 (Debian 11.2.0-20) 11.2.0, GNU ld (GNU Binutils for Debian) 2.38) #1 SMP Debian 5.17.3-1 (2022-04-18)

I can't help with the original question, but just thought I'd say that I downloaded and compiled from source Freepbx/Asterisk on Armbian running on an SDcard and have never had an issue with choppy audio. 

My version is FreePBX 13.0.197.31 which is fairly old as its been running for a few years, but it is still under support.  Im using an orange pi one with 512Mb memory, The PBX which has light use (3 extensions, one PSTN gateway, one IVR, 3 trunks) but does do other stuff as well.

Hi BarnA,

 

I'm looking to create a setup similar to yours. Which ARM SBCs are you using and have you had any luck in finding FXO/FXS boards?

Thanks,

Chas
