I have a show I am running in xLights with several songs. All but Wizards in Winter are in perfect sync. They all use the same Vixen profile. I checked the comm port settings and they OK. The CPU sems to be about 10% busy. I changed the order of the songs but the lag persists only for that song. I verified that Vixen and xLights are using the same audio file. I am at wits end. Does anyone have any suggestions?
