Appreciate the work that you are putting in. Can't be easy in these uncertain times.
I, for one, can say that I haven't had any hardware, software or driver issues with the Virtuoso SE. I personally use the Dolby Atmos Windows app for surround, and it works fantastic.
The one thing I wish I could do is prevent the Virtuoso from muting and unmuting on profile switch. I use auto profile switching (which works less than half the time, but that is a different thread post). Either auto profile switching or manual, the Virtuoso remembers the mute state from profiles so I am constantly having to pay attention to it. Is it possible to remove the Virtuoso from profile switching?
