I had USB audio and windows 10 problems; stuttering after a while of running smoothly.

Finally installed the newest AMD radeon drivers, explicitly the basic version with no gamers' acceleration etc present or active. All worked well with BIAB 2017 and 2018 the first versions and ASIO with a low latency setting (for 2018 it seemed).

Now with 506 i had to switch to MME, as there was clearly distortion present, with the RTs. I haven't sussed it out yet, but tips are welcome ... F
