OK, first system specs... Linux mint 19 Kernel 5.5.19 LowLatency Yeasu FT-857D Yeasu SCU-17 sound interface I'm not sure what else you'd want to know but here's the problem.... When either JS8 or WSJT-X are running after a while and right after a TX the water fall will freeze up (in wsjt-x) or just draw straight lines but both will stop decoding completely. I contacted Jordan about JS8 and he suspected the sound card is going to sleep so I disabled usb suspend but that didn't solve the problem. Sometimes I can quick key a time or two and it'll snap out of it but not always. Anyone have any idea what's going on? I do have RF chokes on everything so I don't think RFI is a issue.
