Hi all
I am playing DXD (352.8kHz FLAC) files to a USB DAC and I am getting intermittent severe distortion which to me sounds like a USB transmission issue caused by DPC latency. My configuration is as follows:
- Win 10 Pro
- jRiver MC21
- Chord Mojo connected over USB using Chord ASIO driver 1.05
- alternatively AudioQuest Dragonfly 2 (downsampling samplerate to 88.2kHz)
I am getting the distortion with both DACs, which would suggest a problem with the XPS 13 HW or SW. I have disabled "Allow the computer to turn off this device to save power" for Intel USB3 eXtensible Host Controller and for the USB Root Hub (xHCI), but that did not solve the issue.
Power Plan is set to high performance, Under advanced settings I have set USB selective suspend setting to disabled.
DPC latency check and Latency Mon do not show any issue and list the PC as being capable of streaming real time audio.
The problem goes away if I chose the direct sound driver in jRiver. It occurs identically if I chose the ASIO, WASAPI and Kernel streaming drivers.
The problem does not occur on an HP zbook 15u.
Does anyone else have a similar problem and has anyone solved it?
