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and m1 for some years as mini PBX with asterisk, due the stop of bananian's development that works perfectly but now is obsolete and vulnerable, i'm testing armbian but registered prompt audio sounds choppy and i can't find reasons, I tried to move files in ram disk, use usb to lan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.
