Happy new year to all, I was using VAC 4.15 with my Flex 5000A without any problem Yesterday, I tried the new VAC 4.5 and got a fatal error ! I tested many potential solutions without any success Any idea ? Thierry - F5LHF.
As mentioned in the manual, 4.50 supports RTAudio KS communication protocol and defaults to it if available (Vista/7/8/8.1/10). Some KS applications support only legacy KS protocol so you need to switch render/capture port types in VAC Control Panel.
