did you take a look at the attenuation setting in Daphile? Maybe adjusting that will help if you haven't already. And there are buffer settings too that might need to be changed.

Spent quite some time messing around with that.

I believe the processor is too slow.

Thanks, it was worth a shot.

  Oh well. The other option is in the power settings. I was able to lower the processor speed. Maybe you can increase it?

    I can increase the power settings. I set the processor speed to adaptive and that worked for PCM. Looks like i9 processors or higher would be good for upsampling to DSD512.
    
    This whole experiment seems possible, I looked at the availability of i9 machines and then said I am happy upsampling to 768khz PCM instead with my small low power Celeron linux PC.
    
    The sound at 768khz PCM sounds great. I've played back some 24bit/32bit 384khz and it sounds pretty nice. Keep in mind this is all over USB. I have doubts USB 2.0 can even handle DSD512 I didn't look at that critically in terms of bandwidth.
    
    I'm eventually going to try getting into ARM RISC processors for the linux workstations but not for a couple of years. I'm not sure if RISC architecture processes DSD more efficiently. If that's true that would mean a better way could be Libre PC. Although I don't see anyone here talking about that.
