Posted in 3rd Party Hardware and not getting any feedback, so trying here....

Ran into an issue with Transporter down sampling everything to 96 kHz when I synchronize. Transporter is connected via coax to Krell Digital Vanguard integrated amp. LMS is 8.2. Decided to try moving one of my Raspberry pi 4 with piCorePlayer 8.0 to replace the Transporter to see if that would fix the problem. Well, it did... however, .dsf files and .flac files at his-res play, but with a hiss in the background. HDMI is connected to Raspberry pi slot 0 next to power connection and then connected to Krell Digital Vanguard Integrated Amp HDMI port. I've run through all the output settings with no success. Also tried changing DSD settings in piCorePlayer to 3:32be, 3:16be and 3:u8. No issues with playing at 44kHz, just Hi-resolution files.

Appreciate any help.
