I couldn't get the WAS driver to work properly on the desktop after loading Build 512 (tremendous latency problems....I reported this to PG).
To me this is the major clue. You write like you understand this stuff but someway, somehow you're missing something simple. WAS works absolutely perfect with the vast majority of users. It's a huge improvement in Windows sound. What did Support have to say about using WAS?
On your laptop, I would switch to WAS and if that doesn't work then I would say it's with the laptop itself. FWIW, another user spent weeks (seriously, weeks) messing around with stuff like this and wound up reinstalling Windows and voila everything's perfect. That tells me that somehow he messed up his system with something.
On a clean system, Biab runs perfectly, simple as that. Sure, it's possible now that a recent Win10 update may require a tweak but I haven't seen that yet and I'm on automatic updates.

See prior thread regarding Build 512 and WAS driver:
http://www.pgmusic.com/forums/ubbthreads.php?ubb=showflat&Number=457835#Post457835Microsoft is going to start pushing out Release 4 for Windows 10 in April. If you re-load Windows now, it will be overwritten by Release 4 at some point, unless you turn off Updates, in which case you stop getting the monthly Updates, which is not a good idea in this day and age. Microsoft's got the system rigged. I might as well wait and see what happens after Release 4 is installed.
Also, remember that my HP i3 desktop is not stuttering, but my HP i5 laptop is. Both systems have 8 GB RAM. Running the Steinberg AIO buffer up to 1538 samples was a test, which didn't eliminate the stutter, so I can crank it back down to 512 samples or so. The laptop is communicating to the Steinberg via the USB interface, so there is the possibility that something's going on with the laptop hardware configuration that may be problematical. I'm waiting to see if Steinberg has anything to say about this.
One advantage of Windows 7 was that you could pick and choose the Windows Updates, only installing those you wanted. They then killed that ability for users when they started issuing only monthly cumulative rollups for Windows 7 about a year ago.
