Has anyone tried this, I asked Jussi, it should work (the email conversation below on vinyl streaming w/ Korg DAC-10R / HQPlayer / Roon is edited for brevity)?
rthorntn: “Can I buy HQPlayer and use it to stream vinyl from a turntable w/ADC to endpoints, preferably using DSD and continue to use Roon for my library?”
jussi: "RME ADI-2 Pro is the recommended DSD capable ADC for such purposes. Works up to DSD256 on all three supported platforms. Generally all three platforms share same functionality. Audio driver interfaces are different on different OS. If the Korg DAC-10R supports DSD on Linux either through native of through DoP, it should work.
First make normal output from standalone HQPlayer work to a NAA. Then you can configure Roon to use HQPlayer as a playback engine.
Then you can try to configure the Korg as input device to HQPlayer. Then you can select wanted input format from the drop-list on HQPlayer main window and hit enter, this loads it on the playlist (appears below) and then you can press Play to start capture/processing/playback."
