November 13, 20241 yr I run a audio loop code on a Raspberry pi 4/5 and Orange Pi 5. The latency of audio loop is 0.2 seconds on Raspberry pi but on orange pi it takes 1.2 seconds. For orange pi, i am facing this problem with different Operating systems as well apart from armbian. I've used Ubuntu, Orange Pi OS, Armbian. All have got this problem. The code I have attached. Since the issue is faced in multiple Operating System I strongly feel this has to do with the driver level softwares or directly related optimization from Rockchip. Can anyone guide what I could do audio-loop.cpp
