OK, an update on this:
I’m going through and recreating mreid’s settings in my HQP (on the CX), and then playing a DSD128 file in Roon through the HQP CX > NAA EX chain.
Changing DSD Sources > Integrator = IIR to FIR still crashed, neither did changing the Output mode settings. (still crashed with Auto, PCM, or SDM)
I did turn of Auto rate family, not sure if that interacts with the below
All at once, I changed
- 1x / Nx oversampling from poly-sinc-ext2 to closed-form-16m
- modulator from ASDM7ECv2 to DSD7 256+fs
- Bit rate from 5644800 to Auto
This enabled me to play back a DSD 128 file uninterrupted for about 5 minutes. Then it cut out, and the Roon app on my laptop lost connection with the server. The CX seems to be running pretty warm (in my 17 degrees c room) but of course I can’t confirm the CPU load until Antipodes give us the CPU monitor functionality again.
After waiting for the Roon UI to come back, I tried to play a DSD 256 file, but it won’t play, and I within seconds lost the Roon UI again.
