A couple of comments after reading "Why is this happening with BIAB and not RealBand"? and "Exit BIAB and the signal is clean again."

It appears you've tried different audio interfaces and drivers, but I didn't see a mention of buffers. For recording, I set that low, but for playback with no problems, I often raise it. This certainly applies to ASIO drivers; I'm not sure about WAS since that doesn't work on my system. And I agree you should stay away from the internal RealTek soundcard for any serious work.

I have occasionally read comments here that say, "My DAW works fine, so why doesn't BIAB"? BIAB can load and run on a modest machine, but even though I haven't read any statement from the company saying this, I think the most recent version does seem to demand a lot more in computer resources if you have many tracks regenerating. This is something DAWs do not do. On a computer without many cores in the CPU to share the load as they now do, I could anticipate a problem.
