If you are using Voicemeeter Banana (VMB), you can make the PowerSDR to VMB connection using ASIO. Everything else, e.g. WSJT-X, will connect to VMB using whatever method it wants, as VMB supports all Windows sound drivers. This way you can use ASIO where possible, but fall back to MME or other drivers as required, and PowerSDR remains insulated from all of these issues by VMB.AB2EZ wrote:To my knowledge, WSJT-X only works with MME and 48000 samples per second.
