Are you talking about the kernel in the "native DSD kernel " thread? https://www.snakeoil-os.net/forums/attac...hp?aid=342
I tried already to download, drag and drop in the load window in SO but it wouldn't work. I assumed it was because it was old/old thread.
I am on 1.2.10, using Intel Atom 3900, ubuntu 22.04.1 LTS.
My DAC is Lampizator Big 7 MKII, (JL Sounds which is on your list here I believe )-it works with native DSD/DSF using SO/ MPD, also works with Daphile/LMS for native DSD/DSF with Daphile version of squeezelite.
