    Can't you just disable jack detection?

    I have been creating a program to send and get the responses for Intel HDA verbs and params. The "get" verbs work well, however the first set verb I tried - reset (mentioned aboved) - fails (the response is all 0s, including the "valid" bit). When trying the HDA Utility program it reports that the "chk" driver is necessary for setting. What is this driver? On a related note how does a program receive unsolicited responses after enabling them? Thanks!

    chk versions of Windows (including hdaudio.sys) are available via MSDN subscription. I don't know whether the HD Audio driver will relay unsolicited responses up through the debug interface; I suspect not.  You might need to write a custom HD Audio function driver to capture those. What is your scenario where you need to see the verbs directly?  If you like you can email me privately: mateer at microsoft dot com

    My original plan was to make an app like all the custom ones that audio driver providers ship with their drivers, but much more stream-lined (all of those usually are overly graphical, etc). I understand that the Sound control panel does many of those things. I also wanted to be able to do automated things based on pin events (pin connect / disconnect). I haven't got anywhere near that far and for the moment I am instead working on a program similar to HDAU just to be able to see all the data that is there.
