I have a little problem of recognition sound card Nvidia, in practice, when you turn off your PC and the next day its not restart this would be recognized as default sound system, not connected, to better understand attach screen.

I too have had this problem and I (think) I found a solution. You can create an EDID override for your display so that Windows thinks it is on all the time. I thought this was valuable enough that I wrote a guide about how to do it:

How To - Fix Loss of HDMI Audio After Resume from Sleep

Nice guide Warner. A quick question. For this to work is it mandatory to disable test mode again or should it work fine without?
Because I have a WHS 2011 and if I disable test mode it messes up my Infrared driver somehow.

PS. I can say also the pin19 trick work, at least for me.
