Skyler, I’ll have to disagree with your statements completely. I have not only personally load-tested but I have and know of many high traffic systems that are running with zero “sputter” or issue.l on a Pi. Several have been on the air and running for well over a year. I am also running one system in conjunction with DMRLink and transcoding audio (read a much heavier demand on System resources) from DMR <-> Analog with no “sputter”. Granted the transcoding is offloaded to a separate chip but nonetheless. On all of these systems running on a Pi 2 or 3 the system load from asterisk, DMRLink etc all combined never exceeds 15% and the audio is always clean ( not withstanding network craziness ). So having said all of this I would look elsewhere for what may be causing your audio ailments. I can’t really point you in a specific direction other than to review overall system load and performance inline with general system administration best practices. And of course standard troubleshooting methods of hardware swapping/testing and validation. JJC N0PKT Sent from the iRoad, so please ignore any typos or awesome autocorrects

At this point, I don't think the raspberry pi audio is as good as it could be on the raspberry pi. Even with a pi 3 on the best settings in usbradio, it will sputter every once and a while I realize Doug has implemented a precision timer, however, his image is not open source, and I cannot modify, therefore not an option for me.
What is the best mini computer hardware available for reasonable prices nowadays that I could use in place of the pi? The raspberry pi arm architecture just does not seem to cut the current versions of AllStar and DAHDI. I realize how picky I am being, but I am sort of going crazy by some raspberry pi nodes i've put together with crazy sputtering issues. And the telemetry sometimes sounds like it is played at 1/2 speed. U
Usbradio and simpleusb have their different problems, but neither seem to work ok. I would actually argue usbradio works better on the pi because it does not have an unreliable duplex audio delay.
Do ATOM processers work well? Best suggestions here for something lightweight and non power-hungry?
Thank You! Skyler KDØWHB
