J.L., you again? Man, how many times do I have to be indebted to your keen talents! Thank you, I am thinking that I checked this box but I suspect you have found the problem. Er, once again!
No wait… Hm. I do have this box checked. And I can see the Stereo output playing, but there is no sound from my monitors. It is similar to the other issues I had, as if a Control Room feature is on or something. But I have the Control Room disabled. ??? What in the world, one more time.
I do remember that this feature worked at some point, but after some update or alteration I might have made to C5, it stopped. It is nice, obviously, when it works because you might hear something wrong as the mixdown happens. Too, it passes the time a little better, than to just sit there in the silence.
