I think it would be better to focus on the bigger issue which is the sound card problem.Hi Chris,
the (Not found) annotation means exactly what it says. The underlying Qt framework functionality we use to enumerate audio devices did not list the one you last used in WSJT-X. If the drop down list is also empty then no audio devices are available to WSJT-X.
MS Windows has several audio sub-systems, the one we have access to is called MME (Multi-Media Extensions). If MME is unable to enumerate your audio devices then the problem lies within MS Windows and your best source of support is probably with Microsoft support. A basic question like "I am using an application that uses MME audio and it can't see any audio devices, what should I do?" seems pertinent.
If you are happy to download and run a pre-built executable from me, the following application will enumerate the audio devices seen by MME using just MS system library code without any of the framework layers we use in WSJT-X, it would be interesting to see the output:
The source code is here if you want to know what it does or prefer to build it yourself:
