I just updated to version 5.0-RC1-83 and I would like to mention an issue with DSD reproduction with MPD 0.21.6:
when reproducing DSD tracks (I tried both tracks in DSD 64 and 128) there is an annoying background noise/hiss.
Two additional notes:
Adding below some details on one of the test files used (I can provide them if needed) and the Khadas USB DAC used.
Thanks
franz

Two additional notes:
- the noise disappears and the reproduction is correct when using MPD 0.20.20
- the issue was there also in previous RC0 and RC1 versions
