I also use foobar2000 and I have specified the "DSD : ASIO : TUSBAudio ASIO Driver as output for the R6Pro.So some of my DSD files play beautifully with just WASAPI selected, while others sound like there is a waterfall in the background.
When I switch to DSD: WASAPI: the waterfall disappears, but then other DSD albums won't play at all.
I noticed that the files with high noise are albums from one specific vendor...
Thoughts on settings in Foobar2k or on the unit I should change?
Thus, mp3, flac and DSD iso files were played without problems.
However, I only connected the R6Pro for a short time because I prefer to use my chord mojo as a DAC.
