Sonore OpticalRendu feeding USB to LKS DA-004 DAC with upgraded Amanero USB board.
Description Of Issue
My DA-004 DAC can accept all DSD rates. The drop down where you select the DSD upsampling rate only shows DSD 64 and 128 as choices. Why? I want to also try upsampline to DSD 256 and 512.
What does Roon check in my network and/or hardware to decide NOT to display the two higher DSD rates in the drop down?
Here are the DAC Diagnostics run from SonicOrbiter in case those are helpful.
I have selected DSD 128 and it does work, but there are several types of errors occurring. A “sandpaper” like noise for a second or so occasionally, some drop outs and when music is paused some odd sounds now and then when there should be dead silence. I suspect these may be due to some as yet unknown issue with my network. The cable modem and router are on top floor of my home and the ST, fiber media converter and optical Rendu are in basement. I have a 50’ length of cat 7 ethernet cable run from top floor to basement, plugged into a Trendnet 5 port Gigabit Greennet switch.
I have set the SDM Gain Adjustment to - 6 db.
Thanks, Bob
