MC 21, exaSound E22, DSD4 Upsampling not working

And is there anything I can do to get Native DSD 4 files to play (which won't, even though it will upsample PCM to DSD4)?
Awesome Donkey:
Running the benchmark will tell us how powerful your machine is. DSD can be pretty intensive on the CPU, especially multichannel.

Hi, Well, this morning it’s working, upsampling to DSD 4!!!
I had the Buffer set too low.
First try after resetting didn’t upsample, but the 2nd try it started working.
User error! Thanks alot for your replies!

2 channel only. Are you saying it is more CPU intensive for JRiver to play DSD256 files than to convert PCM to DSD256 on the fly? Seems a bit strange. DSD256 plays fine on Audirvana, HQPlayer, Decibel, etc on this computer, and PCM files converted to DSD256 on-the-fly play fine. Here's the Benchmark:

That's a little better than the average new machine.
