Hi @Margaret_Simmonds and @dspreadbury ,
at the time Margaret created the diagnostics report, Dorico was already set to the Generic Low Latency ASIO driver, therefore I propose to rather use the Xonar DG ASIO driver instead and see how that one goes, because in general, dedicated ASIO drivers to an audio interface or built-in soundchip are to be preferred over any generic driver.
But should that Xonar DG ASIO driver also not work, then it is time to try out the FlexASIO driver. Or the Steinberg built-in ASIO driver, as can be downloaded from the link given in my posting here.
Should you still not be able to get any sound, send me a private message and we can arrange for a remote screen sharing session.
