Ah well. That is on AVSForum. I know I have an account there from years ago, and tried to reset my password, but every thing I entered for a new password I just get a rejection saying "Please enter a valid password" without giving me a clue as to what would make it valid. I had a run-in with one of their moderators a long while back with extremely solid skull shielding to ward off thoughts contrary to his half baked assumptions before, so I guess he took over their front end user interface programming duties too. BTW, perhaps it is just me, but don't they allow just casual viewers there any longer without having to register and log in?
So, in a nutshell, I guess if my answer is on AVSForum, then my question will remain unanswered.
Anyway, fyi, it looks like ASIO might work on my laptop, but I haven't tried it with the HDMI cable hooked up to my Denon receiver yet. On the laptop itself the two outputs simply select either the left or the right speaker. Seeking the frequency response of those laptop speakers is interesting in it's own right, I guess. Maybe tomorrow I will find the time to try the laptop on my home theater system again. But I wish there was a way to select ALL of the speakers together so I could get an image that way of what is going on in the room in the way of frequency interactions. Or perhaps there is if everything is working correctly in the setup?
Thanks anyway.
