I am running Roon 2.0 build 1353 with the lastest firmware on Zidoo Neo S v6.7.66. When I use the internal dac I can get every type of file from 88khz t0 192khz to DSD 256 to play bit perfect. However, for all my 44.1 khz files no matter what I try it is upsampling them to 48 khz. I have made sure to have all the setting in MUSE disabled. Is Zidoo telling Roon it can't play 44.1 khz files? Anybody have any idea what may be happening here? I have searched everywhere I can think of for an answer but I seem to be the only one with the problem (or the only one who cares?) All music files are FLAC. System: Roon Server v2.0 build 1353 running on SonicTransport software version 2.8. Zidoo Neo S firmware 6.7.66. Analog out to Parasound preamp via balanced cables
